■ Memories – Up to 256 KB Flash program memory (10k W/E cycles, retention 20 yrs @ 85°C) – 16 KB Read-While-Write Flash for data (100k W/E cycles, retention 20 yrs@ 85°C) – Flash Data Readout and Write Protection – 16KBytes embedded high speed SRAM – Memory mapped interface (SMI) to ext.
Serial Flash (64 MB) w.
boot capability
■ Clock, reset and supply management – Single supply 3.
3V ±10% or 5V ±10% – Embedded 1.
8V Voltage Regulators – Int.
RC for fast start-up and backup clock – Up to 60 MHz operation using internal PLL with 4 or 8 MHz crystal/ceramic osc.
– Smart Low Power Modes: SLOW, WFI, STOP and STANDBY with backup registers – Real-time Clock, driven by low power internal RC or 32.
768 kHz dedicated osc, for clock-calendar and Auto Wake-up
■ Nested interrupt controller – Fast interrupt handling with 32 vectors – 16 IRQ priorities, 2 maskable FIQ sources – 16 external interrupt / wake-up lines
■ DMA – 4-channel DMA controller – Circular buffer management – Support for UART, SSP, Timers, ADC
■ 6 Timers – 16-bit watchdog timer (WDG) – 16-bit timer for system timebase functions – 3 synchronizable timers each with up to 2 input captures and 2 output compare/PWMs.
