80C51 with 512 B/1 kB/2 kB RAM, dual I2C-bus, SPI

I Idle mode

2.3 Comparison to the P89C660/662/664 devices

I SPI interface. The P89V660/662/664 devices include an SPI interface that was not

present on the P89C660/662/664 devices.

I Dual I2C-bus interfaces. The P89V660/662/664 devices have two I2C-bus interfaces.

The P89C660/662/664 devices have one.

I More I/O pins. The P89V660/662/664 devices have an additional four-bit I/O port,

Port 4.

I The 6x/12x mode on theP89V660/662/664 devices is programmable and erasable

using ISP and IAP as well as parallel programmer mode. The P89C660/662/664

devices could only be switched using parallel programmer mode.

I Smaller block sizes. The smallest block size on the P89C660/662/664 devices was

8 kB. The P89V660/662/664 devices have a page size of 128 B. These small pages

can be erased and reprogrammed using IAP function calls making use of the code

memory for non-volatile data storage practical. Each page erase is 30 ms or less. The

IAP and ISP code in P89V660/662/664 devices support these 128-byte page

operations. In addition, the IAP and ISP code uses multiple page erase operations to

emulate the erasing of the larger block sizes (8 kB and 16 kB to maintain ﬁrmware

compatibility).

I Status bit versus Status byte. The P89V660/662/664 devices used a Status byte to

control the automatic entry into ISP mode following a reset. On the P89V660/662/664

devices this has changed to a single Status bit. Since the ISP entry was based on the

zero/non-zero value of the Status byte this is an almost identical operation on the

P89V660/662/664 devices.

I Faster block erase. The erase time for the entire user code memory of the

P89V660/662/664 devices is 150 ms.
