MCU 32Bit Flash:32KB SRAM:8KB
16-bit/32-bit ARM7TDMI-S microcontroller in a tiny LQFP48 package.
n 2 kB/4 kB/8 kB of on-chip static RAM and 8 kB/16 kB/32 kB of on-chip flash program
memory. 128-bit wide interface/accelerator enables high-speed 70 MHz operation.
n ISP/IAP via on-chip bootloader software. Single flash sector or full chip erase in
100 ms and programming of 256 bytes in 1 ms.
n EmbeddedICE RT offers real-time debugging with the on-chip RealMonitor software.
n The 10-bit A/D converter provides eight analog inputs, with conversion times as low as
2.44 ms per channel and dedicated result registers to minimize interrupt overhead.
n Two 32-bit timers/external event counters with combined seven capture and seven
n Two 16-bit timers/external event counters with combined three capture and seven
n Low power Real-Time Clock (RTC) with independent power and dedicated 32 kHz
n Multiple serial interfaces including two UARTs (16C550), two Fast I2C-buses
(400 kbit/s), SPI and SSP with buffering and variable data length capabilities.
Vectored interrupt controller with configurable priorities and vector addresses.
n Up to thirty-two 5 V tolerant fast general purpose I/O pins.
n Up to 13 edge or level sensitive external interrupt pins available.
n 70 MHz maximum CPU clock available from programmable on-chip PLL with a
possible input frequency of 10 MHz to 25 MHz and a settling time of 100 ms.
n On-chip integrated oscillator operates with an external crystal in the range from 1 MHz
to 25 MHz.
n Power saving modes include Idle mode, Power-down mode with RTC active, and
n Individual enable/disable of peripheral functions as well as peripheral clock scaling for
additional power optimization.
n Processor wake-up from Power-down mode via external interrupt or RTC.
