P89LPC9381
Description
The P89LPC9381 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 P89LPC9381 in order to reduce component count, board space, and system cost.
Key Features
- 1 Principal features I 4 kB byte-erasable flash code memory organized into 1 kB sectors and 64 B pages. Single-byte erasing allows any byte(s) to be used as non-volatile data storage. I 256 B RAM data memory on-chip RAM. I 8-input multiplexed 10-bit ADC. Two analog comparators with selectable inputs and reference source. I 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 RTC. I 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. I High-accuracy internal RC oscillator option allows operation without external oscillator components. The RC oscillator option is selectable and fine tunable. I 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). I 28-pin TSSOP package with 23 I/O pins minimum and up to 26 I/O pins while using on-chip oscillator and reset options.
