NXP 87C52EBPN 8-Bit CMOS Microcontroller DIL-40

Product Description

NXP 8-Bit CMOS Microcontrollers
- NXP 87C52EBPN, The 87C52 is a high-performance static 80C51 design fabricated with high-density CMOS technology with operation from 2.7 V to 5.5 V. Contains a 256 x 8 RAM, 32x I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, & on-chip oscillator & clock circuits. In addition, the device is a low power static design which offers a wide range of operating frequencies down to zero. Two software selectable modes of power reduction-idle mode & power-down mode are available. The idle mode freezes the CPU while allowing the RAM, timers, serial port, & interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative. Since the design is static, the clock can be stopped without loss of user data & then the execution resumed from the point the clock was stopped. NXP 87C52EBPN 8-Bit CMOS Microcontroller DIL-40
