P87C51MB2 - 80C51 8-bit microcontroller family with extended memory

General Description

The P87C51Mx2 represents the first microcontroller based on Philips Semiconductors’ new 51MX core.

Key Features

  • 96 kbytes of OTP program memory and 3 kbytes of data SRAM, while the P87C51MB2 has 64 kbytes of OTP and 2 kbytes of RAM. In addition, both devices are equipped with a Programmable Counter Array (PCA), a watchdog timer that can be configured to different time ranges through SFR bits, as well as two enhanced UARTs and Serial Peripheral Interface (SPI). Philips Semiconductors’ 51MX (Memory eXtension) core is an accelerated 80C51 architecture that executes instructions at twice the rate of standard 8.
