– 3 V to 3.6V operating supply range for A/ D
when single channel), conversion range 0-2.5V.

■ Three Serial Communication Interfaces (UART)
– 1.8V operating supply range for core supply
allow full duplex, asynchronous,
provided either by internal Voltage Regulator
communications with external devices,
with external stabilization capacitor, or by ex-
independently programmable TX and RX baud
ternal supply for higher power efficiency.
rates up to 625K baud.
■ 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.

■ 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 I2C Interfaces provide multi-master and
slave functions, support normal and fast I2C
mode (400KHz), 7/10 bit addressing modes.
One I2C Interface is multiplexed with one SPI,
so either 2xSPI+1xI2C or 1xSPI+2xI2C may be
