CMOS M8T (0.18 um) technology.
-40°C to 85°C operating temperature range.
144-pin TQFP144 package or 64-pin TQFP64
package
Power Supply:
– 2.7V to 3.6V operating supply range for Input/
– 3 V to 3.6V 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

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
