with

the

ARM7 family of processors

– 8 KByte Instruction + Data cache, 4-way

set-associative

– Write buffer de-coupling CPU from system

memory during write operations

– MMU

for

virtual

to

physical

address

mapping and memory protection

■ Memories

– 16 KBytes Program RAM Memory

– External SDRAM Interface for up to 128

Mbytes SDRAM

– External Memory Interface (EMI) for up to 8

Mbytes SRAM, Flash, ROM.

– ATAPI interface supporting PIO4 mode

■ Nested interrupt controller

– Fast interrupt handling with multiple vectors

– 32 vectors with 16 IRQ priority levels

– 2 maskable FIQ sources

■ Clock, Reset and Supply Management

– Internal system clocks generated by fully

internal PLL

– Power

management

providing

different

operating modes: RUN, SLOW, STOP,

STANDBY.

■ 34 I/O ports

– 34 multifunctional bidirectional I/O lines

– 5 ports with interrupt capability

■ 3 Timers

– Two 16-bit programmable Timer modules

with prescaler (fAPB divided by 1 to 256)

driven

from

internal

selectable

clock

(oscillator or CPU clock), output compare

and input capture functions.

– 16-bit Watchdog Timer with 8-bit prescaler

■ 6 Communications Interfaces

– USB v 2.0 Full Speed (12Mbit/s) Device

Function

with

Suspend

and

Resume

support

– CAN module compliant with the CAN

specification V2.0 part B (active).

– Two High-Speed Universal Asynchronous

Receiver Transmitter (UART) for full-duplex

asynchronous communication.

– Two Buffered Serial Peripheral Interfaces

(BSPI)

for

full-duplex,

synchronous,

communications

with

external

devices,

master or slave operation.

■ A/D Converter

– Sigma Delta Analog/Digital Converter with

11.5-bit ENOB resolution supporting 4

multiplexed inputs at up to 950 Hz sampling

rate.

■ Development Tools Support

– 5-pin JTAG port (IEEE 1149.1 Standard)
