C 1 61 K / O
The Basi c 16-bit Microcontrollers
C 1 6 1 K / O M E M B E R S of the C166 family offer all benefits of a full
16-bit controller at the average price of an 8-bit controller. The C161 product
range is focused on price sensitive applications such as in consumer
products. Grouped around the 25 MHz C166 core a variety of basic
peripherals have been chosen for optimal product and system costs.
