Description:

8-BIT MICROCOMPUTER UNIT

Features

* 32 TTL/CMOS COMPATIBLE I/O LINES 24 BIDIRECTIONAL (8 lines are LED compatible) 8 INPUT-ONLY 3776 BYTES OF USER ROM 112 BYTES OF RAM SELF-CHECK MODE ZERO-CROSSING DETECT/INTERRUPT INTERNAL 8-BIT TIMER WITH 7-BIT SOFTWARE PROGRAMMABLE PRESCALER AND CLOCK SOURCE 5V SINGLE SUPPLY SOFTWARE FEATURES 10 PO

Applications

* PPORT PINT and can be neglected. PPORT may become significant if the device is configured to drive Darlington bases or sink LED loads. An approximate relationship between PD and TJ (if PPORT is neglected) is : PD = K + (TJ + 273C) (2) Solving equations 1 and 2 for K gives : K = PD. (TA + 273C) + JA. P
