Revision A6  
W78C32C/W78C032C  
1. GENERAL DESCRIPTION  
The W78C032C microcontroller supplies a wider frequency range than most 8-bit microcontrollers on  
the market. It is compatible with the industry standard 80C32 microcontroller series.  
The W78C032C contains four 8-bit bidirectional parallel ports, three 16-bit timer/counters, and a serial  
port. These peripherals are supported by a six-source, two-level interrupt capability. There are 256  
bytes of RAM, and the device supports ROMless operation for application programs.  
The W78C032C microcontroller has two power reduction modes, idle mode and power-down mode,  
both of which are software selectable. The idle mode turns off the processor clock but allows for  
continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power  
consumption. The external clock can be stopped at any time and in any state without affecting the  
1.processor.

W78C32C/W78C032C  
4. PIN DESCRIPTION  
P0.0P0.7  
Port 0, Bits 0 through 7. Port 0 is a bidirectional I/O port. This port also provides a multiplexed low  
order address/data bus during accesses to external memory.  
P1.0P1.7  
Port 1, Bits 0 through 7. Port 1 is a bidirectional I/O port with internal pull-ups. Pins P1.0 and P1.1 also  
serve as T2 (Timer 2 external input) and T2EX (Timer 2 capture/reload trigger), respectively.  
P2.0P2.7  
Port 2, Bits 0 through 7. Port 2 is a bidirectional I/O port with internal pull-ups. This port also provides  
the upper address bits for accesses to external memory.  
P3.0P3.7  
Port 3, Bits 0 through 7. Port 3 is a bidirectional I/O port with internal pull-ups. All bits have alternate  
functions, which are described below:

External Address Input, active low. This pin forces the processor to execute out of external ROM. This  
pin should be kept low for all W78C032C operations.  
RST  
Reset Input, active high. This pin resets the processor. It must be kept high for at least two machine  
cycles in order to be recognized by the processor.  
ALE  
Address Latch Enable Output, active high. ALE is used to enable the address latch that separates the  
address from the data on Port 0. ALE runs at 1/6th of the oscillator frequency. A single ALE pulse is  
skipped during external data memory accesses. ALE goes to a high state during reset with a weak  
pull-up.

W78C32C/W78C032C  
5. FUNCTIONAL DESCRIPTION  
The W78C032C architecture consists of a core controller surrounded by various registers, four  
general purpose I/O ports, 256 bytes of RAM, three timer/counters, and a serial port. The processor  
supports 111 different instruction and references both a 64K program address space and a 64K data  
storage space.  
5.1 Timers 0, 1, and 2  
Timers 0, 1, and 2 each consist of two 8-bit data registers. These are called TL0 and TH0 for Timer 0,  
TL1 and TH1 for Timer 1, and TL2 and TH2 for Timer 2. The TCON and TMOD registers provide  
control functions for timers 0, 1. The T2CON register provides control functions for Timer 2. RCAP2H  
and RCAP2L are used as reload/capture registers for Timer 2.  
The operations of Timer 0 and Timer 1 are the same as in the W78C31. Timer 2 is a special feature of  
the W78C032C: it is a 16-bit timer/counter that is configured and controlled by the T2CON register.  
Like Timers 0 and 1, Timer 2 can operate as either an external event counter or as an internal timer,  
depending on the setting of bit C/T2 in T2CON. Timer 2 has three operating modes: capture, auto-  
reload, and baud rate generator. The clock speed at capture or auto-reload mode is the same as that  
of Timers 0 and 1.  
5.2 Clock  
The W78C032C is designed to be used with either a crystal oscillator or an external clock. Internally,  
the clock is divided by two before it is used. This makes the W78C032C relatively insensitive to duty  
cycle variations in the clock.  
5.2.1 Crystal Oscillator  
The W78C032C incorporates a built-in crystal oscillator. To make the oscillator work, a crystal must  
be connected across pins XTAL1 and XTAL2. In addition, a load capacitor must be connected from  
each pin to ground, and a resistor must also be connected from XTAL1 to XTAL2 to provide a DC bias  
when the crystal frequency is above 24 MHz.  
5.2.2 External Clock  
An external clock should be connected to pin XTAL1. Pin XTAL2 should be left unconnected. The  
XTAL1 input is a CMOS-type input, as required by the crystal oscillator. As a result, the external clock  
signal should have an input one level of greater than 3.5 volts.  
5.3 Power Management  
5.3.1 Idle Mode  
The idle mode is entered by setting the IDL bit in the PCON register. In the idle mode, the internal  
clock to the processor is stopped. The peripherals and the interrupt logic continue to be clocked. The  
processor will exit idle mode when either an interrupt or a reset occurs.  
- 6 -  
 
W78C32C/W78C032C  
5.3.2 Power-down Mode  
When the PD bit of the PCON register is set, the processor enters the power-down mode. In this  
mode all of the clocks, including the oscillator are stopped. The only way to exit power-down mode is  
by a reset.  
5.3.3 Reset  
The external RESET signal is sampled at S5P2. To take effect, it must be held high for at least two  
machine cycles while the oscillator is running.  
An internal trigger circuit in the reset line is used to deglitch the reset line when the W78C032C is  
used with an external RC network. The reset logic also has a special glitch removal circuit that ignores  
glitches on the reset line.  
During reset, the ports are initialized to FFH, the stack pointer to 07H, PCON (with the exception of bit  
4) to 00H, and all of the other SFR registers except SBUF to 00H. SBUF is not reset.

6.3 A.C. Characteristics  
The AC specifications are a function of the particular process used to manufacture the part, the ratings  
of the I/O buffers, the capacitive load, and the internal routing capacitance. Most of the specifications  
can be expressed in terms of multiple input clock periods (TCP), and actual parts will usually  
experience less than a ±20 nS variation. The numbers below represent the performance expected  
from a 0.5 micron CMOS process when using 2 and 4 mA output buffers.
