1. General description
The P87C51Mx2 represents the first microcontroller based on Philips
Semiconductors’ new 51MX core. The P87C51MC2 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 80C51 devices.
The linear address range of the 51MX has been expanded to support up to 8 Mbytes
of program memory and 8 Mbytes of data memory. It retains full program code
compatibility to enable design engineers to re-use 80C51 development tools,
eliminating the need to move to a new, unfamiliar architecture. The 51MX core also
retains 80C51 bus compatibility to allow for the continued use of 80C51-interfaced
peripherals and Application Specific Integrated Circuits (ASICs).
The P87C51Mx2 provides greater functionality, increased performance and overall
lower system cost. By offering an embedded memory solution combined with the
enhancements to manage the memory extension, the P87C51Mx2 eliminates the
need for software work-around. The increased program memory enables design
engineers to develop more complex programs in a high-level language like C, for
example, without struggling to contain the program within the traditional 64 kbytes of
program memory. These enhancements also greatly improve C Language efficiency
for code size below 64 kbytes.
The 51MX core is described in more detail in the 51MX Architecture Reference.
