PRODUCT INFORMATION
CDC 3231G
The new CDC 3231G-Cx is a pin-compati-
ble mask ROM derivative of Micronas’
32-bit Car Dashboard Controller family
based on an ARM7TDMI
(CDC 32xxG).
The new device comes along with addi-
tional features of the Cx platform like a
superior power saving module (PSM) and
one
V2.0B). Main characteristics of the PSM are
three additional low-power modes (IDLE,
WAKE, and STANDBY), an internal RC
oscillator, a polling/Flash timer output, as
well as an RTC (Real Time Clock).
The device also contains the patented built-
in ERM (EMI Reduction Module).
