High-performance and low power, the HCS08 does not sacrifice performance to provide low power 1.8 V operation.

HCS08 Features — Multiple power management modes, including a 20 nanoamp (nA) power-down mode.

• A zero-component auto-wakeup from "stop" to help reduce costs and reduce power to 0.7 microamp (uA) - Up to 40 MHz CPU/20 MHz bus at 2.1 V and 16 MHz CPU/8 MHz bus at 1.8 V
• A programmable internal clock generator with temperature and voltage compensation (typical drift < 2%) designed for reliable communications, fast start up and reduced system cost
• In-application reprogramming and data storage via third-generation 0.25µ flash technology
• High integration including four serial communication ports, up to 8 timer/PWMs, and an 8-channel 10-bit analog-to-digital converter specified down to 1.8 V.
