P89LPC9381
P89LPC9381 is 8-bit microcontroller manufactured by NXP Semiconductors.
.. 8-bit microcontroller with accelerated two-clock 80C51 core 4 k B 3 V byte-erasable flash with 10-bit ADC Rev. 01 - 8 September 2006 Product data sheet 1. General 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 ponent count, board space, and system cost. 2. Features 2.1 Principal Features I 4 k B byte-erasable flash code memory organized into 1 k B 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 parators 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 bee 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 k Hz byte-wide I2C-bus munication port and SPI munication port. I High-accuracy internal RC oscillator option allows operation without external oscillator ponents. 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. .. Philips Semiconductors 8-bit microcontroller with 10-bit ADC 2.2 Additional Features I 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...
