87C451 Datasheet (NXP) - 80C51 8-bit microcontroller family 4K/128 OTP/ROM/ROMless/ expanded I/O

87C451 - 80C51 8-bit microcontroller family 4K/128 OTP/ROM/ROMless/ expanded I/O

The Philips 8XC451 is an I/O expanded single-chip microcontroller fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes latch-up sensitivity. The 8XC451 (includes the 80C451, 87C451 and 83C451) is a functional extension of the 87C51 microcontroller with three ad

87C451 Features

* except the on-board 4k × 8 ROM. The 87C451 has 4k of EPROM on-chip as program memory and is otherwise identical to the 83C451. The 8XC451 has two software selectable modes of reduced activity for further power reduction; idle mode and power-down mode. Idle mode freezes the CPU while allowing the RAM
