1. General Description
The W79E(L)633 is a fast, 8051/52-compatible microcontroller with a redesigned processor core that
eliminates wasted clock and memory cycles. Typically, the W79E(L)633 executes instructions 1.5 to 3
times faster than that of the traditional 8051/52, depending on the type of instruction, and the overall
performance is about 2.5 times better at the same crystal speed. As a result, with the fully-static
CMOS design, the W79E(L)633 can accomplish the same throughput with a lower clock speed,
reducing power consumption.
The W79E(L)633 provides 256 bytes of on-chip RAM; 1-KB of auxiliary RAM; four 8-bit, bi-directional
and bit-addressable I/O ports; an additional 4-bit port P4; three 16-bit timer/counters; an UART serial
port, 2 channels of I2C with master/slave capability and 4 channels of 10-bit ADC. These peripherals
are all supported by ten interrupt sources with 2 levels of priority.
The W79E(L)633 contains a 128-KB Flash EPROM whose contents may be updated in-system by a
loader program stored in an auxiliary, 4-KB Flash EPROM. Once the contents are confirmed, it can be
protected for security.
Note: If the applied VDD is not stable, especially with long transition time of power on/off, it’s
recommended to apply an external RESET IC to the RST pin for improving the stability of
system.

EXTERNAL ACCESS ENABLE: This pin forces the processor to execute
the external ROM. The ROM address and data are not presented on the bus
if the EA pin is high.

PROGRAM STORE ENABLE: PSEN enables the external ROM data in the
Port 0 address/data bus. When internal ROM access is performed, no PSEN
strobe signal outputs originate from this pin.
ADDRESS LATCH ENABLE: ALE enables the address latch that separates
the address from the data on Port 0.
RESET: Set this pin high for two machine cycles while the oscillator is
running to reset the device.
CRYSTAL 1: Crystal oscillator input or external clock input.
CRYSTAL 2: Crystal oscillator output.
GROUND: ground potential.
POWER SUPPLY: Supply voltage for operation.
PORT 0: 8-bit, bi-directional I/O port with internal pull-up resisters. This port
also provides a multiplexed, low-order address / data bus during accesses to
external memory.
PORT 1: 8-bit, bi-directional I/O port with internal pull-up resistors. This port
also provides alternate functions as below.
P1.0 ~ P1.5 provide PWM0 ~ PWM5.
P1.4 ~ P1.7 provide ADC0 ~ ADC3.
P1.0 alternately provides Timer2 external count input.(T2)
P1.1 alternately provides Timer2 Reload/Capture/Direction control.(T2Ex)
PORT 2: 8-bit, bi-directional I/O port with internal pull-ups. This port also
provides the upper address bits when accessing external memory. P2.4 to
P2.7 can be software configured as I2C serial ports
PORT 3: 8-bit, bi-directional I/O port with internal pull-up resistors.
All bits have alternate functions, which are described below:
RXD (P3.0): Serial Port 0 input
TXD (P3.1): Serial Port 0 output
P3.0P3.7
I/O
SH
INT0 (P3.2): External Interrupt 0
INT1(P3.3): External Interrupt 1
T0 (P3.4):Timer 0 External Input
T1 (P3.5):Timer 1 External Input
WR (P3.6): External Data Memory Write Strobe
P4.0P4.3
I/O
SH
RD (P3.7): External Data Memory Read Strobe
PORT 4: 4-bit bi-directional I/O port. The P4.3 also provides the alternate
function REBOOT which is H/W reboot from LD flash.
* Note : TYPE I: input, O: output, I/O: bi-directional, H: pull-high, L: pull-low, D: open drain S: Schmitt Trigger
