CDC 3257G

ARM7-Based Car Dashboard Controller

The CDC 3257G-Cx is a pin-compatible

◆ RTC delivering hours, minutes, seconds

◆ Polling/Flash timer output

◆ Two I C master modules

Flash ROM derivate of Micronas’ 32-bit Car

Dashboard Controller family based on an

ARM7TDMI CPU core (CDC32xxG).

◆ Seven stepper motor drivers

◆ PLL circuitry delivering up to 50 MHz

◆ 4- to 5-MHz oscillator

◆ Six PWM modules

(configurable as 2×8 bit or 1×16 bit)

This device comes along with additional

features of the Cx platform like a superior

power saving module (PSM), two high-

speed CAN modules (Bosch V2.0B) and a

device lock module to inhibit Flash access.

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).

◆ Pulse frequency modulator

◆ EMI reduction module (ERM)

◆ Digital watchdog

◆ Sound generator with auto decay

◆ Two SW-selectable clock outputs

◆ Central clock divider

◆ 16-bit free-running counter with six cap-

◆ Interrupt controller with 40 inputs and

ture/compare modules

16 priority levels

◆ Patch module (up to 10 cells)

◆ Six port interrupts

◆ Device lock module (DLM) inhibiting

◆ Regulator input supervision for reset/

Flash access

alarm (alarm comparator)

◆ 1×16-bit timer and 4×8-bit timer

◆ JTAG interface

The CDC 3257G also contains the patented

built-in ERM (EMI Reduction Module).

◆ Clock and supply supervision

◆ 16-channel 10-bit ADC

◆ Two comparators

◆ −40 to +105 °C case temperature range

Features

◆ Single 3.5 V to 5.5 V supply voltage

◆ ADC reference (1 internal, 3 external)

◆ 48×4 LCD module

◆ 256 KB Flash

◆ 12 KB SRAM

◆ 8 KB boot ROM

(limited I/O performance below 4.5 V)

◆ Up to 102 GPIOs

◆ Three DMA channels

◆ 128-pin PQFP package, 0.5 mm pin pitch

◆ Two UARTs, two SPIs

◆ DigitBus master module

◆ Four CPU operation modes

(Deep Slow, Slow, Fast, PLL)

◆ Two CAN modules with 512 Bytes each

of object RAM according to Bosch speci-

fication V2.0B (32 message objects)

◆ Three low-power modes

(Idle, Wake, Standby)
