Description

The P89C66x, based on the 80C51 family, has up to 64 KB

of Flash program memory and is set apart from other 80C51

derivatives with I

The P89C66x RAM to ROM ratio meets the designer’s

requirement for large data memory when writing C code.

The Flash program memory of the P89C66x supports both

parallel programming and 5 V serial ISP. Parallel-programmable

means the devices can be gang-programmed at high speed, thus

reducing programming costs and time to market. A default serial

loader (boot loader) program in ROM allows serial ISP of the

Flash memory without the need for a loader in the Flash code.

ISP allows a device’s program memory to be altered in the actual

end product. The capability to field-update the application

firmware makes a wide range of applications possible.

In addition, the P89C66x is In-Application Programmable

(IAP). Because the 66x contains a boot ROM, the Flash

program memory can be reconfigured even while the

application is running. User programs may erase and

reprogram the Flash memory at will through the use of

standard routines contained in ROM. With IAP, the

application can be updated remotely with changes or

enhancements in the field even while the application is

running, so there is no downtime or interruption of service.

A key feature of the P89C66x is its fast execution. The design

engineer can chose to run the application with the conventional

80C51 clock rate (12 clocks per machine cycle) or use the

default mode (six clocks per machine cycle) to achieve a

2x throughput improvement with the same clock frequency.

So, a 20 MHz P89C66x becomes a 40 MHz equivalent

microcontroller. Another way to benefit from this feature is to

keep the same throughput by reducing the clock frequency by

half, thus dramatically reducing electromagnetic interference.

Another way to benefit from this feature is to keep the same

throughput by reducing the clock frequency by half, thus

dramatically reducing electromagnetic interference.

The P89C66x is suitable for a wide variety of applications

that benefit from low EMI and the flexibility of Flash ISP

and IAP. It also supports applications that require pulse

width modulation, high-speed I/O and/or up/down counting

capabilities such as motor control. Because the P89C66x

family has I

Platform Management (IPMI) applications in servers and high-

end PCs where I

C, it is also extremely well suited for Intelligent

C serves as physical protocol for the interface.

C and RAM capacity up to 8 K bytes.
