89LPC925
Description
The P89LPC924/925 are single-chip microcontrollers designed for applications demanding high-integration, low cost solutions over a wide range of performance requirements. The P89LPC924/925 is based on a high performance processor architecture that executes instructions in two to four clocks, six times the rate of standard 80C51 devices.
Key Features
- 2.1 Principal features s 4 kB/8 kB Flash code memory with 1 kB erasable sectors, 64-byte erasable page size, and single byte erase
- s 256-byte RAM data memory
- s Two 16-bit counter/timers
- Each timer may be configured to toggle a port output upon timer overflow or to bee a PWM output
- s Real-Time clock that can also be used as a system timer
- s 4-input 8-bit multiplexed A/D converter/single DAC output
- Two analog parators with selectable inputs and reference source
- s 400 kHz byte-wide I2C-bus munication port
- s Configurable on-chip oscillator with frequency range and RC oscillator options (selected by user programmed Flash configuration bits)
- Oscillator options support frequencies from 20 kHz to the maximum operating frequency of 18 MHz
