P89LPC980/982/983/985

8-bit microcontroller with accelerated two-clock 80C51 core,

4 kB/8 kB wide-voltage byte-erasable flash with 10-bit ADC

Rev. 4 — 15 June 2010

Product data sheet

1. General description

The P89LPC980/982/983/985 is a single-chip microcontroller, available in low cost

packages, based on a high performance processor architecture that executes instructions

in two to four clocks, six times the rate of standard 80C51 devices. Many system-level

functions have been incorporated into the P89LPC980/982/983/985 in order to reduce

component count, board space, and system cost.

2. Features and benefits

2.1 Principal features

4 kB/8 kB byte-erasable flash code memory organized into 1 kB sectors and 64-byte

pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.

256-byte RAM data memory. Both the P89LPC982 and the P89LPC985 also include a

256-byte auxiliary on-chip RAM.

8-input multiplexed 10-bit ADC (P89LPC985, 4-input multiplexed 10-bit ADC on

P89LPC983) with window comparator that can generate an interrupt for in or out of

range results. Two analog comparators with selectable inputs and reference source.

Five 16-bit counter/timers (each may be configured to toggle a port output upon timer

overflow or to become a PWM output).

A 23-bit system timer that can also be used as a real-time clock consisting of a 7-bit

prescaler and a programmable and readable 16-bit timer.

Enhanced UART with a fractional baud rate generator, break detect, framing error

detection, and automatic address detection; 400 kHz byte-wide I

C-bus

communication port and SPI communication port.

High-accuracy internal RC oscillator option 7.373 MHz calibrated to

±1

%, with clock

doubler option, allows operation without external oscillator components. The RC

oscillator option is selectable and fine tunable.

Watchdog timer with separate on-chip oscillator, nominal 400 kHz/25 kHz, calibrated to

±10

% at 400 kHz, requiring no external components. The watchdog prescaler is

selectable from eight values.

Pin remap for UART, I

C-bus and SPI.

2.4 V to 5.5 V V

operating range.

Enhanced low voltage (brownout) detect allows a graceful system shutdown when

power fails.

28-pin TSSOP and PLCC packages with 23 I/O pins minimum and up to 26 I/O pins

while using on-chip oscillator and reset options.

2.2 Additional features

A high performance 80C51 CPU provides instruction cycle times of 111 ns to 222 ns

for all instructions except multiply and divide when executing at 18 MHz. This is six

times the performance of the standard 80C51 running at the same clock frequency. A

lower clock frequency for the same performance results in power savings and reduced

EMI.

Serial flash In-Circuit Programming (ICP) allows simple production coding with

commercial EPROM programmers. Flash security bits prevent reading of sensitive

application programs.

Serial flash In-System Programming (ISP) allows coding while the device is mounted

in the end application.

In-Application Programming (IAP) of the flash code memory. This allows changing the

code in a running application.

Clock switching on the fly among internal RC oscillator, watchdog oscillator, external

clock source provides optimal support of minimal power active mode with fast

switching to maximum performance.

Idle and two different power-down reduced power modes. Improved wake-up from

Power-down mode (a LOW interrupt input starts execution). Typical power-down

current is 1

μA

(total power-down with voltage comparators disabled).

Integrated PMU (Power Management Unit) automatically adjusts internal regulators to

minimize power consumption during Idle mode, Power-down mode and Total

power-down mode. In addition, the power consumption can be further reduced in

Normal or Idle mode through configuring regulators modes according to the

applications.

Active-LOW reset. On-chip power-on reset allows operation without external reset

components. A software reset function is also available.

Configurable on-chip oscillator with frequency range options selected by user

programmed flash configuration bits. Oscillator options support frequencies from

20 kHz to the maximum operating frequency of 18 MHz.

Oscillator fail detect. The watchdog timer has a separate fully on-chip oscillator

allowing it to perform an oscillator fail detect function.

Programmable port output configuration options: quasi-bidirectional, open drain,

push-pull, input-only.

High current sourcing/sinking (20 mA) on eight I/O pins (P0.3 to P0.7, P1.4, P1.6,

P1.7). All other port pins have high sinking capability (20 mA). A maximum limit is

specified for the entire chip.

Port ‘input pattern match’ detect. Port 0 may generate an interrupt when the value of

the pins match or do not match a programmable pattern.

Controlled slew rate port outputs to reduce EMI. Outputs have approximately 10 ns

minimum ramp times.

Only power and ground connections are required to operate the

P89LPC980/982/983/985 when internal reset option is selected.

Four interrupt priority levels.

Eight keypad interrupt inputs, plus two additional external interrupt inputs.

Schmitt trigger port inputs.

Second data pointer.

Emulation support.
