The P89C669 represents the ﬁrst Flash microcontroller based on Philips Semiconductors’ new 51MX core.

96 kbytes of Flash program memory and 2 kbytes of data SRAM. In addition, this device is 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 byte based I2C-bus serial interface. Philips Semiconductors’ 51MX (Memory eXtension) core is an accelerated 80C51 architecture that executes instructions at twice the rate of standard 80C51 devices. The linear address range of the 51MX has been.
