Summary

2512JS–AVR–10/06

Note: This is a summary document. A complete document

is available on our Web site at www.atmel.com.

The AVR core combines a rich instruction set with 32 general purpose working registers.

All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing

two independent registers to be accessed in one single instruction executed in one clock

cycle. The resulting architecture is more code efficient while achieving throughputs up to

ten times faster than conventional CISC microcontrollers.

The ATmega8515 provides the following features: 8K bytes of In-System Programmable

Flash with Read-While-Write capabilities, 512 bytes EEPROM, 512 bytes SRAM, an

External memory interface, 35 general purpose I/O lines, 32 general purpose working

registers, two flexible Timer/Counters with compare modes, Internal and External inter-

rupts, a Serial Programmable USART, a programmable Watchdog Timer with internal

Oscillator, a SPI serial port, and three software selectable power saving modes. The Idle

mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and Interrupt

system to continue functioning. The Power-down mode saves the Register contents but

freezes the Oscillator, disabling all other chip functions until the next interrupt or hard-

ware reset. In Standby mode, the crystal/resonator Oscillator is running while the rest of

the device is sleeping. This allows very fast start-up combined with low-power

consumption.

The device is manufactured using Atmel’s high density nonvolatile memory technology.

The On-chip ISP Flash allows the Program memory to be reprogrammed In-System

through an SPI serial interface, by a conventional nonvolatile memory programmer, or

by an On-chip Boot program running on the AVR core. The boot program can use any

interface to download the application program in the Application Flash memory. Soft-

ware in the Boot Flash section will continue to run while the Application Flash section is

updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU

with In-System Self-programmable Flash on a monolithic chip, the Atmel ATmega8515

is a powerful microcontroller that provides a highly flexible and cost effective solution to

many embedded control applications.

The ATmega8515 is supported with a full suite of program and system development

tools including: C Compilers, Macro assemblers, Program debugger/simulators, In-cir-

cuit Emulators, and Evaluation kits.

Disclaimer

Typical values contained in this datasheet are based on simulations and characteriza-

tion of other AVR microcontrollers manufactured on the same process technology. Min

and Max values will be available after the device is characterized.

The ATmega8515 provides all the features of the AT90S4414/8515. In addition, several

AT90S4414/8515 in most cases. However, some incompatibilities between the two

microcontrollers exist. To solve this problem, an AT90S4414/8515 compatibility mode

can be selected by programming the S8515C Fuse. ATmega8515 is 100% pin compati-

ble with AT90S4414/8515, and can replace the AT90S4414/8515 on current printed

circuit boards. However, the location of Fuse bits and the electrical characteristics dif-

fers between the two devices.

Programming the S8515C Fuse will change the following functionality:

•

The timed sequence for changing the Watchdog Time-out period is disabled. See

“Timed Sequences for Changing the Configuration of the Watchdog Timer” on page

53 for details.

The double buffering of the USART Receive Registers is disabled. See “AVR

USART vs. AVR UART – Compatibility” on page 137 for details.

PORTE(2:1) will be set as output, and PORTE0 will be set as input.

Pin Descriptions

VCC

GND

Port A (PA7..PA0)

Digital supply voltage.

Ground.

Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port A output buffers have symmetrical drive characteristics with both high sink

and source capability. When pins PA0 to PA7 are used as inputs and are externally

pulled low, they will source current if the internal pull-up resistors are activated. The Port

A pins are tri-stated when a reset condition becomes active, even if the clock is not

running.

Port A also serves the functions of various special features of the ATmega8515 as listed

on page 67.

Port B (PB7..PB0)

Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port B output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port B pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port B also serves the functions of various special features of the ATmega8515 as listed

on page 67.

Port C (PC7..PC0)

Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port C output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port C pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port D output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port D pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port D also serves the functions of various special features of the ATmega8515 as listed

on page 72.

Port E(PE2..PE0)

Port E is an 3-bit bi-directional I/O port with internal pull-up resistors (selected for each

bit). The Port E output buffers have symmetrical drive characteristics with both high sink

and source capability. As inputs, Port E pins that are externally pulled low will source

current if the pull-up resistors are activated. The Port E pins are tri-stated when a reset

condition becomes active, even if the clock is not running.

Port E also serves the functions of various special features of the ATmega8515 as listed

on page 74.

RESET

Reset input. A low level on this pin for longer than the minimum pulse length will gener-

ate a reset, even if the clock is not running. The minimum pulse length is given in Table

18 on page 46. Shorter pulses are not guaranteed to generate a reset.

Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.

Output from the inverting Oscillator amplifier.
