80C51 Microcontroller - 4T

Part No. N79E352_N79E352R
Datasheet  N79E352_N79E352R.pdf
Description The N79E352(R) is an 8-bit Turbo 51 microcontroller which has Flash EPROM programmable hardware writer. The instruction set of the N79E352(R) is fully compatible with the standard 8052. The N79E352(R) contains a 8Kbytes of main Flash EPROM; a 256 bytes of RAM; 128 bytes NVM Data Flash EPROM; three 16-bit timer/counters; 2-channel 8-bit PWM; 1-channel UART and 1 additional input capture. These peripherals are supported by 11 interrupt sources four-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the N79E352(R) allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security. N79E352(R) is designed for cost effective applications which can serve industrial devices, and other low power applications.
Features
  • Fully static design 8-bit Turbo 51 CMOS microcontroller up to 24 MHz when VDD=4.5V to 5.5V, 12MHz when VDD=2.7V to 5.5V, and 4MHz when VDD=2.4V to 5.5V.
  • 8K bytes of AP Flash EPROM, with external writer programmable mode.
  • 256 bytes of on-chip RAM.
  • 128 bytes NVM Data Flash EPROM for customer data storage used and 10 k writer cycles.
