Rev. 1004D–09/01

chip, the Atmel AT90S2323/2343 is a powerful microcontroller that provides a highly

flexible and cost-effective solution to many embedded control applications.

The AT90S2323/2343 AVR is supported with a full suite of program and system devel-

opment tools including: C compilers, macro assemblers, program debugger/simulators,

in-circuit emulators and evaluation kits.

Comparison between

AT90S/LS2323 and

AT90S/LS2343

The AT90S/LS2323 is intended for use with external quartz crystal or ceramic resonator

as the clock source. The start-up time is fuse-selectable as either 1 ms (suitable for

ceramic resonator) or 16 ms (suitable for crystal). The device has three I/O pins.

The AT90S/LS2343 is intended for use with either an external clock source or the inter-

nal RC oscillator as clock source. The device has five I/O pins.

Table 1 summarizes the differences in features of the two devices.

Pin Descriptions

AT90S/LS2323

VCC

GND

Port B (PB2..PB0)

Supply voltage pin.

Ground pin.

Port B is a 3-bit bi-directional I/O port with internal pull-up resistors. The Port B output

buffers can sink 20 mA. As inputs, Port B pins that are externally pulled low, will source

current if the pull-up resistors are activated.

Port B also serves the functions of various special features.

Port pins can provide internal pull-up resistors (selected for each bit). The Port B pins

are tri-stated when a reset condition becomes active.

RESET

Reset input. An external reset is generated by a low level on the RESET pin. Reset

pulses longer than 50 ns will generate a reset, even if the clock is not running. 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.
