General description

The P89LPC952/954 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 P89LPC952/954 in order to reduce component count,

board space, and system cost.

Features

2.1 Principal features

I 8 kB/16 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 and a 256-byte auxiliary on-chip RAM.

I 8-input multiplexed 10-bit ADC with window comparator that can generate an interrupt

for in or out of range results. 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) and a 23-bit system timer that can also be used

as a RTC.

I Two enhanced UARTs 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 High-accuracy internal RC oscillator option, with clock doubler option, allows operation

without external oscillator components. The RC oscillator option is selectable and ﬁne

tunable. Fast switching between the internal RC oscillator and any oscillator source

provides optimal support of minimal power active mode with fast switching to

maximum performance.

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

driven to 5.5 V).

I 44-pin and 48-pin packages with 40 and 42 I/O pins minimum while using on-chip

oscillator and reset options.

I Port 5 has high current sourcing/sinking (20 mA) for all Port 5 pins. All other port pins

have high sinking capability (20 mA). A maximum limit is speciﬁed for the entire chip.

I Watchdog timer with separate on-chip oscillator, requiring no external components.

The watchdog prescaler is selectable from eight values.
