P89LPC915/916/917
8-bit microcontrollers with accelerated two-clock 80C51 core
2 kB 3 V Flash with 8-bit A/D converter
Rev. 04 — 17 December 2004
Product data
1. General description
The P89LPC915/916/917 are single-chip microcontrollers in low-cost 14-pin and
16-pin 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 P89LPC915/916/917 in order
to reduce component count, board space, and system cost.
2. Features
www.DataSheet4U.com
s 2 kB byte-erasable Flash code memory organized into 256-byte sectors and
16-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile
data storage.
s 256-byte RAM data memory.
s Two 16-bit counter/timers. Timer 0 (and Timer 1 - P89LPC917) may be configured
to toggle a port output upon timer overflow or to become a PWM output.
s 23-bit system timer that can also be used as a Real-Time clock.
s 4-input multiplexed 8-bit A/D converter/single DAC output. Two analog
comparators with selectable reference.
s Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
s SPI communication port (P89LPC916).
s Internal RC oscillator option allows operation without external oscillator
components. The RC oscillator (factory calibrated to ±1 %) 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 Up to 14 I/O pins when using internal oscillator and reset options (P89LPC916,
P89LPC917).
3. Additional features
14-pin (P89LPC915) and 16-pin (P89LPC916, P89LPC917) TSSOP packages.
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.
