C 1 61 P I
Consumer Class 16-bit Microcontroller
T H E C 1 6 1 P I is a new 16-bit entry-level microcontroller particularly
well suited for low cost, low power and high performance Consumer or
Telecom applications.
B A S E D O N our C166 core, this flexible microcontroller comes with
a host of useful peripherals, such as on-chip Real Time Clock, fast 10-bit
ADC, as well as various clock generation schemes. It also incorporates
serial interfaces, such as I2C and USART, making communications easy with
other devices in target applications.
T H I S C O M B I N A T I O N of carefully selected features together with
flexible power management provides designers with the required flexibility
and an excellent price-performance ratio-improving system performance
while lowering system costs.
