P89LPC9151/9161/9171  
8-bit microcontroller with accelerated two-clock 80C51 core,  
2 kB 3 V byte-erasable flash with 8-bit ADC  
Rev. 02 — 9 February 2010  
Product data sheet  
1. General description  
The P89LPC9151/9161/9171 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 device in order to reduce component count,  
board space, and system cost.  
2. Features  
2.1 Principal features  
„ 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.  
„ 256-byte RAM data memory.  
„ 4-input multiplexed 8-bit ADC/single DAC output. Two analog comparators with  
selectable inputs and reference source.  
„ Two 16-bit counter/timers. Timer 0 (and Timer 1 - P89LPC9171) may be configured to  
toggle a port output upon timer overflow or to become a PWM output.  
„ 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.  
„ 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.  
„ SPI communication port (P89LPC9161).  
„ 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).  
„ Enhanced low voltage (brownout) detect allows a graceful system shutdown when  
power fails.  
„ 16-pin TSSOP with 12 I/O pins minimum and up to 14 I/O pins while using on-chip  
oscillator and reset options (P89LPC9161/9171), and 14-pin TSSOP packages with 10  
I/O pins minimum and up to 12 I/O pins while using on-chip oscillator and reset options  
(P89LPC9151).
