P89LPC9301/931A1

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

4 kB/8 kB 3 V byte-erasable ﬂash

Rev. 01 — 9 April 2009

Preliminary data sheet

1. General description

The P89LPC9301/931A1 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 P89LPC9301/931A1 in order to reduce component count,

board space, and system cost.

2. Features

2.1 Principal features

I 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 Two analog comparators with selectable inputs and reference source.

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 and SPI 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 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

I 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.

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

commercial EPROM programmers. Flash security bits prevent reading of sensitive

application programs.
