retention 20 years at 55°C after 10 kcycles
- ^{Data memory up to 1 Kbytes true data}
EEPROM; endurance 300 kcycles
• ^{RAM: Up to 2 Kbytes}
Clock, reset and supply management
• ^{2.95 V to 5.5 V operating voltage}
Flexible clock control, 4 master clock sources:
• _{- Low power crystal resonator oscillator}

- ^{Internal low power 128 kHz RC}
• ^{Clock security system with clock monitor}
Power management:
• _{- Low power modes (wait, active-halt, halt)}
- ^{Switch-off peripheral clocks individually}
• Permanently active, low consumption power-on
and power-down reset
Interrupt management
• ^{Nested interrupt controller with 32 interrupts}
• ^{Up to 37 external interrupts on 6 vectors}
Timers
• 2x 16-bit general purpose timers, with 2+3
CAPCOM channels (IC, OC or PWM)
• Advanced control timer: 16-bit, 4 CAPCOM
channels, 3 complementary outputs, dead-time
insertion and flexible synchronization
• ^{8-bit basic timer with 8-bit prescaler}
• ^{Auto wake-up timer}
• ^{Window and independent watchdog timers}
Communications interfaces
• UART with clock output for synchronous
operation, Smartcard, IrDA, LIN
• ^{SPI interface up to 8 Mbit/s}
• ^{I2C interface up to 400 Kbit/s}
Analog-to-digital converter (ADC)
• 10-bit, ±1 LSB ADC with up to 10 multiplexed
channels, scan mode and analog watchdog
I/Os
• Up to 38 I/Os on a 48-pin package including 16
high sink outputs
• Highly robust I/O design, immune against current
injection
Development support
