P89LPC9201/9211/922A1/9241/

9251

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

2 kB/4 kB/8 kB 3 V byte-erasable ﬂash with 8-bit ADC

Rev. 01 — 16 April 2009

Preliminary data sheet

1. General description

The P89LPC9201/9211/922A1/9241/9251 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 device in order to reduce

component count, board space, and system cost.

2. Features

2.1 Principal features

I 2 kB/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.

I 256-byte RAM data memory.

I 4-input multiplexed 8-bit ADC/single DAC output (P89LPC9241/9251). Two analog

comparators with selectable inputs and reference source.

I On-chip temperature sensor integrated with ADC module (P89LPC9241/9251).

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

overﬂow or to become a PWM output).

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

prescaler and a programmable and readable 16-bit timer.

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

detection, and automatic address detection; 400 kHz byte-wide I²C-bus

communication port.

I 2.4 V to 3.6 V V_DDoperating range. I/O pins are 5 V tolerant (may be pulled up or

driven to 5.5 V).

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

power fails.

I 20-pin TSSOP and DIP packages with 15 I/O pins minimum and up to 18 I/O pins

while using on-chip oscillator and reset options.
