1. General description

The P89C669 represents the ﬁrst Flash microcontroller based on Philips

Semiconductors’ new 51MX core. The P89C669 features 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 I

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 P89C669 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 P89C669 eliminates the need

for software work-arounds. 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 P89C669 device contains a non-volatile Flash program memory that is both

parallel programmable and serial In-System and In-Application Programmable.

In-System Programming (ISP) allows the user to download new code while the

microcontroller sits in the application. In-Application Programming (IAP) means that

the microcontroller fetches new program code and reprograms itself while in the

system. This allows for remote programming over a modem link. A default serial

loader (boot loader) program in ROM allows serial In-System programming of the

Flash memory via the UART without the need for a loader in the Flash code. For

In-Application Programming, the user program erases and reprograms the Flash

memory by use of standard routines contained in ROM.

The 51MX core is described in more detail in the 51MX Architecture Reference .
