P89LPC9102/9103/9107
8-bit microcontrollers with two-clock accelerated 80C51 core
1 kB 3 V byte-erasable Flash with 8-bit A/D converter
Rev. 02 鈥?11 April 2005
Product data sheet
1. General description
The P89LPC9102/9103/9107 are single-chip microcontrollers in low-cost 10-pin and
14-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 P89LPC9102/9103/9107 in order
to reduce component count, board space, and system cost.
2. Features
2.1 Principal features
s
1 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
128-byte RAM data memory.
s
Two 16-bit timer/counters (P89LPC9102/9107). Two 16-bit timers (P89LPC9103)
s
23-bit system timer that can also be used as a RTC.
s
Four input multiplexed 8-bit A/D converter/single DAC output. One analog comparator
with selectable reference.
s
Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities
(P89LPC9103/9107).
s
High-accuracy internal RC oscillator option, factory calibrated to 1 %, allows operation
without external oscillator components. The RC oscillator option is selectable and 鏗乶e
tunable.
s
V
DD
operating range of 2.4 V to 3.6 V with 5 V tolerant I/O pins (may be pulled up or
driven to 5.5 V).
s
Up to 10 (P89LPC9107) or eight (P89LPC9102/9103) I/O pins when using internal
oscillator and reset options.
s
Ultra-small 10-pin HVSON package (P89LPC9102/9103). 14-pin TSSOP
(P89LPC9107).
2.2 Additional features
s
A high performance 80C51 CPU provides instruction cycle times of 136 ns to 272 ns
for all instructions except multiply and divide when using the internal 7.3728 MHz RC
oscillator in clock doubling mode (111 ns to 222 ns when using an external 18 MHz
clock). A lower clock frequency for the same performance results in power savings and
reduced EMI.
