P89LPC936 概述

P89LPC936是一款低成本单片封装微控制器。P89LPC936基于高性能的处理架构，执行指令仅需2到4个时钟周期，速度是标准80C51器件的6倍。P89LPC936集成了多种系统级功能，以便极大减少元件数目和减小电路板面积，从而降低系统成本。

P89LPC936 特性

• 16 kB byte-erasable flash code memory organized into 2 kB sectors and 64-byte pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage.
• 512-byte RAM data memory.
• 512-byte customer data EEPROM on chip allows serialization of devices, storage of setup parameters, etc.
• Dual 4-input multiplexed 8-bit A/D converters/DAC outputs.Two analog comparators with selectable inputs and reference source.
• 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 an RTC.
• Enhanced UART with 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.
• Capture/Compare Unit (CCU) provides PWM, input capture, and output compare functions
• High-accuracy internal RC oscillator option allows operation without external oscillator components.The RC oscillator option is selectable and fine tunable.
• 2.4 V to 3.6 V V_DD operating range. I/O pins are 5 V tolerant (may be pulled up or driven to 5.5 V).
• 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.
