80C51 LPC Microcontroller

Part No. W79E834A/W79E833A/W79E832A
Datasheet  W79E834_W79E833_W79E832.pdf
Description W79E834 is an 8-bit Turbo 51 microcontroller which has Flash EPROM which can be programmed by ICP (In Circuit Program) or by writer. The instruction sets of the W79E834 are fully compatible with the standard 8052. W79E834 contains a 8K bytes of main Flash EPROM; a 256 bytes of AUX RAM; 256 bytes AUX-RAM; three 8-bit bi-directional, one 2-bit bi-directional and bit-addressable I/O ports; three 16-bit timer/counters; 8-channel multiplexed 10-bit A/D converter; 4-channel 10-bit PWM; one timer with input capture units; two serial ports that include a SPI and an enhanced full duplex serial port. These peripherals are supported by 13 sources of four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside W79E834 allow the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security.
