Features Incorporates the ARM7TDMI ARM ® Thumb ® Processor Core High-performance 32-bit RISC Architecture High-density 16-bit Instruction Set Leader in MIPS/Watt Embedded ICE (In-Circuit Emulation) 136K Bytes of On-chip SRAM 32-bit Data Bus Single-clock Cycle Access Fully-programmable External Bus Interface (EBI) Maximum External Address Space of 64M Bytes Up to Eight Chip Selects Software Programmable 8-/16-bit External Data Bus 8-level Priority, Individually Maskable, Vectored Interrupt Controller Four External Interrupts, Including a High-priority Low-latency Interrupt Request 32 Programmable I/O Lines Three-channel 16-bit Timer/Counter Three External Clock Inputs Two Multi-purpose I/O Pins per Channel Two USARTs Two Dedicated Peripheral Data Controller (PDC) Channels per USART Programmable Watchdog Timer Advanced Power-saving Features CPU and Peripherals Can be Deactivated Individually Fully Static Operation: 0 Hz to 33 MHz Internal Frequency Range at 3.0 V, 85°C 1.8V to 3.6V Operating Range Available in a 100-lead TQFP Package Description The AT91R40807 microcontroller is a member of the Atmel AT91 16-/32-bit microcon- troller family, which is based on the ARM7TDMI processor core. This processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. In addition, a large number of internally banked reg- isters result in very fast exception handling, making the device ideal for real-time control applications. The AT91R40807 microcontroller features a direct connection to off-chip memory, including Flash, through the fully-programmable External Bus Interface (EBI). An eight-level priority vectored interrupt controller, in conjunction with the Peripheral Data Controller, significantly improves the real-time performance of the device. The device is manufactured using Atmel’s high-density CMOS technology. By combin- ing the ARM7TDMI processor core with a large on-chip high-speed SRAM and a wide range of peripheral functions on a monolithic chip, the AT91R40807 is a powerful microcontroller that offers a flexible and high-performance solution to many compute- intensive embedded control applications.

2 AT91R40807 1367C–01/02 Absolute Maximum Ratings* DC Characteristics The following characteristics are applicable to the Operating Temperature range: T A = -40 ° C to +85 ° C, unless otherwise specified and are certified for a Junction Temperature up to T J = 100°C. Operating Temperature (Industrial) .... -40 ° C to + 85 ° C *NOTICE: Stresses beyond those listed under “Absolute Maxi- mum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
