1. Overview
The M16C/26A group (M16C/26A, M16C/26T) of single-chip microcomputers is built using the high-perfor-
mance silicon gate CMOS process using a M16C/60 Series CPU core and is packaged in a 42-pin and 48-
pin plastic molded QFP. These single-chip microcomputers operate using sophisticated instructions featur-
ing a high level of instruction efficiency. With 1M bytes of address space, they are capable of executing
instructions at high speed. In addition, this microcomputer contains a multiplier and a DMAC which com-
bined with fast instruction processing capability, makes it suitable for control of various OA, communication,
and industrial equipment which requires high-speed arithmetic/logic operations.
There is a Normal-ver. for M16C/26A and T-ver. and v-ver. for M16C/26T.
1.1 Applications
Audio, cameras, office equipment, communications equipment, portable equipment,
home appliances (inverter solution), auotmotives, etc
