W79E532A/W79L532A

5. FUNCTIONAL DESCRIPTION

The W79E(L)532 is 8052 pin compatible and instruction set compatible. It includes the resources of

the standard 8052 such as four 8-bit I/O Ports, three 16-bit timer/counters, full duplex serial port and

interrupt sources.

The W79E(L)532 features a faster running and better performance 8-bit CPU with a redesigned core

processor without wasted clock and memory cycles. it improves the performance not just by running at

high frequency but also by reducing the machine cycle duration from the standard 8052 period of

twelve clocks to four clock cycles for the majority of instructions. This improves performance by an

average of 1.5 to 3 times. It can also adjust the duration of the MOVX instruction (access to off-chip

data memory) between two machine cycles and nine machine cycles. This flexibility allows the

W79E(L)532 to work efficiently with both fast and slow RAMs and peripheral devices. In addition, the

W79E(L)532 contains on-chip 1KB MOVX SRAM, the address of which is between 0000H and

03FFH. It only can be accessed by MOVX instruction; this on-chip SRAM is optional under software

control.

The W79E(L)532 is an 8052 compatible device that gives the user the features of the original 8052

device, but with improved speed and power consumption characteristics. It has the same instruction

set as the 8051 family. While the original 8051 family was designed to operate at 12 clock periods per

machine cycle, the W79E(L)532 operates at a much reduced clock rate of only 4 clock periods per

machine cycle. This naturally speeds up the execution of instructions. Consequently, the W79E(L)532

can run at a higher speed as compared to the original 8052, even if the same crystal is used. Since

the W79E(L)532 is a fully static CMOS design, it can also be operated at a lower crystal clock, giving

the same throughput in terms of instruction execution, yet reducing the power consumption.

The 4 clocks per machine cycle feature in the W79E(L)532 is responsible for a three-fold increase in

execution speed. The W79E(L)532 has all the standard features of the 8052, and has a few extra

peripherals and features as well.

I/O Ports

The W79E(L)532 has four 8-bit ports and one extra 4-bit port. Port 0 can be used as an Address/Data

bus when external program is running or external memory/device is accessed by MOVC or MOVX

instruction. In these cases, it has strong pull-ups and pull-downs, and does not need any external pull-

ups. Otherwise it can be used as a general I/O port with open-drain circuit. Port 2 is used chiefly as

the upper 8-bits of the Address bus when port 0 is used as an address/data bus. It also has strong

pull-ups and pull-downs when it serves as an address bus. Port 1 and 3 act as I/O ports with alternate

functions. Port 4 serves as a general purpose I/O port as Port 1 and Port 3.

Serial I/O

The W79E(L)532 has one enhanced serial ports that are functionally similar to the serial port of the

original 8052 family. However the serial ports on the W79E(L)532 can operate in different modes in

order to obtain timing similarity as well. The serial port has the enhanced features of Automatic

Address recognition and Frame Error detection.
