CMOS M8T (0.18 µm) technology.

-40°C to 85°C operating temperature range.

Packaged in TQFP 64-pin or 144-pin

Power supply:

– 2.7V to 3.6V operating supply range for

– 3V to 3. V operating supply range for A/ D

– 1.8V operating supply range for core supply

0-66MHz internal clock frequency managed by

a reset and clock control unit; the unitisable to

provide low power modes (Wait, Slow, Stop,

Standby) and to generate the internal clock from

the external reference through integrated PLL.

48 programmable general purpose I/O, each

pin programmable independently as digital

input or digital output; 40 (30 in TQFP64) are

multiplexed with peripheral functions; 16 can

generate an interrupt on input level/transition

Real time clock module with 3 2 kHz low power

oscillator and separate power supply to

continue running during stand-by mode.

Converter reference

provided either by internal voltage regulator

with external stabilization capacitor, or by

external supply for higher power efficiency.

32-bit single chip baseband controller

16-bit watchdog timer with 8 bits prescaler for

system reliability and integrity.

CAN module compliant with the CAN

specification V2.0 part B (active). The bit rate

can be programmed up to 1 MBaud.

Four16-bit programmable timers with 7 bit

prescaler, up to two input capture/output

compare, one pulse counter function, one

PWM channel with selectable frequency each.

4 channels 12-bit sigma-delta analog to digital

converter, single channel or multi channel

conversion modes, single-shotor continuous

conversion modes, sample rate1KHz (4 KHz

when single channel), conversion range 0-2.5V.

Three serial communication interfaces (UART)

allow full duplex, asynchronous,

communications with external devices,

independently programmable TX and RX baud

rates up to 625K baud.

One UART adapted to suit smart card interface

needs, for asynchronous SC as defined by ISO

7816-3; it includes SC clock generation..

Two serial peripheral interfaces (SPI) allow full

duplex, synchronous communications with

external devices, master or slave operation,

max baud rate: 8Mb/s. One SPI may be used

as multimedia card interface.

Two I

slave functions, support normal and fast I

mode (400 kHz), 7/10 bit addressing modes.

One I

so either 2xSPI+1xI

used at a time.

USB unit V1.1 compliant, software configurable

end point setting, USB Suspend/Resume

support. (TQFP144 only)

High Level Data Link Controller (HDLC) unit

supports full duplex operating mode, NRZ,

NRZI, FM0 and MANCHESTER modes,

internal 8bit Baud Rate Generator.

C interfaces provide multi-master and

C interface is multiplexed with one SPI,
