P89LPC933/934/935
8-bit microcontroller with accelerated two-clock 80C51 core
4 kB/8 kB 3 V byte-erasable Flash with 8-bit A/D converters
Rev. 04 — 09 February 2004
Objective data
1. General description
The P89LPC933/934/935 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 P89LPC933/934/935 in order
to reduce component count, board space, and system cost.
2. Features
2.1 Principal features
s 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.
s 256-byte RAM data memory. (P89LPC935 also includes a 512-byte auxiliary
on-chip RAM).
s 512-byte customer Data EEPROM on chip allows serialization of devices, storage
of set-up parameters, etc. (P89LPC935)
s Dual 4-input multiplexed 8-bit A/D converters (P89LPC935, single A/D on
P89LPC934/933). Two analog comparators with selectable inputs and reference
source.
s 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 Real-Time clock.
s Enhanced UART with fractional baudrate generator, break detect, framing error
detection, and automatic address detection; 400 kHz byte-wide I2C-bus
communication port and SPI communication port.
s Capture/Compare Unit (CCU) provides PWM, input capture, and output compare
functions (P89LPC935).
s High-accuracy internal RC oscillator option allows operation without external
oscillator components.The RC oscillator option is selectable and fine tunable.
s 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).
s 28-pin TSSOP, PLCC, and HVQFN packages with 23 I/O pins minimum and up to
26 I/O pins while using on-chip oscillator and reset options.
