P80C851FFA datasheet

Description :

The Philips 80C851/83C851 is a high-performance microcontroller fabricated with Philips high-density CMOS technology. The 80C851/83C851 has the same instruction set as the 80C51. The Philips CMOS technology combines the high speed and density characteristics of HMOS with the low power attributes of CMOS. The Philips epitaxial substrate minimizes latch-up sensitivity. The 80C851/83C851 contains a 4k ×8 ROM with mask-programmable ROM code protection, a 128 ×8 RAM, 256 ×8 EEPROM, 32 I/O lines, two 16-bit counter/timers, a seven-source, five vector, two-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits.

ATmega328P PDF – 8-bit AVR RISC-based Microcontroller

Part Number : ATmega328P

Function : 8-bit AVR RISC-based Microcontroller

Package : TQFT, MLF 32 Pin

Manufactuerers : ATMEL -> Microchip


ATmega328P datasheet


The ATmega328P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega48A / PA/ 88A / PA / 168A / PA /328 / P achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The device operates between 1.8-5.5 volts.
