UPD78C10ACW

The UPD78C10ACW is designed as 8-bit single-chip microcomputer (with a/d converter) which is a ROM-less product of the UPD78C11A, and can directly address the external memory up to 64k bytes.

UPD78C10ACW has twelve features. (1) Abundant 159 types of instructions : 87AD series instruction set, multiplication/division instructions, 16-bit operation instructions. (2) Instruction cycle : 0.8 ms (at 15 MHz operation). (3) On-chip ROM would be non. (4) On-chip RAM : 256W x 8. (5) High-precision 8-bit A/D converter : 8 analog inputs. (6) General-purpose serial interface : asynchronous, synchronous, I/O interface mode. (7) Multi-function 16-bit timer/event counter. (8) Two 8-bit timers. (9) I/O lines would be 32. (10) Interrupt function (external - 3, internal - 8): non-maskable interrupt x 1, maskable interrupt x 10. (11) Standby function : HALT mode, hardware/software STOP mode. (12) Zero-cross detection function : (2 inputs). That are all the main features.

Some absolute maximum ratings of UPD78C10ACW have been concluded into several points as follow. (1) Its power supply voltage would be from -0.5V to +7.0V for Vdd and would be from AVss to Vdd+0.5V for AVdd and would be from -0.5V to +0.5V for AVss. (2) Its input voltage would be from -0.5V to Vdd+0.5V. (3) Its output voltage would be from -0.5V to Vdd+0.5V. (4) Its output current low would be 4.0mA for all output pins and would be 100mA for total of all output pins. (5) Its output current high would be -2.0mA for all output pins and would be -50mA for total of all output pins. (6) Its A/D converter reference input voltage would be from -0.5V to AVdd+0.3V. (7) Its operating ambient temperature range would be from -40 to +85°C. (8) Its storage temperature range would be from -65°C to +150°C. It should be noted that even if one of the parameters exceeds its absolute maximum rating even momentarily, the quality of the product may be degraded. And so on.
