... Available in a 120-ball BGA Package Description The AT91FR40161 is a member of the Atmel AT91 16/32-bit Microcontroller family, which is based on the ARM7TDMI processor core. The processor has a high-perfor- mance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. A large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications ...

... Flash. The AT91 Flash Uploader software is able to upload program application software into its Flash memory. The AT91FR40161 integrates several peripherals that are classified as system or user peripherals. All on-chip peripherals are 32-bit accessible by the AMBA Bridge, and can be pro- grammed with a minimum number of instructions ...

... It is recommended that in any application phase, the inputs to the microcontroller be held at valid logic levels to minimize the power consumption. The AT91FR40161 has a fully static design and works on the Master Clock (MCK), pro- vided on the MCKI pin from an external source. The Master Clock is also provided as an output of the device on the pin MCKO, which is multiplexed with a general purpose I/O line ...

... SRAM while the application is running, a write detection feature has been implemented. The AT91FR40161 also integrates a 2 Mbyte Flash memory that is accessed via the External Bus Interface. All data, address and control lines, except for the Chip Select signal, are connected within the device. ...

... The External Bus Interface features also the Early Read Protocol, configurable for all the devices, that significantly reduces access time requirements on an external device in the case of single-clock cycle access. In the AT91FR40161, the External Bus Interface connects internally to the Flash memory. The 2 Mbyte Flash memory is organized as 1,048,576 words of 16 bits each. The Flash memory is addressed as 16-bit words via the EBI ...

... USART0 RXD1 USART1 The Flash Uploader requires the embedded Flash to be used as the AT91FR40161 boot memory and a valid clock to be applied to MCKI. After reset, the Flash Uploader imme- diately recopies itself into the internal SRAM and jumps to it. The following operation requires this memory resource only ...

... Peripheral Data Controller 6040B–ATARM–03/04 The AT91FR40161 has a 4-channel PDC dedicated to the two on-chip USARTs. One PDC channel is dedicated to the receiver and one to the transmitter of each USART. The user interface of a PDC channel is integrated in the memory space of each USART. It contains a 32-bit Address Pointer Register (RPR or TPR) and a 16-bit Transfer Counter Register (RCR or TCR) ...

... The AIC also features a spurious vector detection feature, which reduces spurious inter- rupt handling to a minimum, and a protect mode that facilitates the debug capabilities. The AT91FR40161 has 32 programmable I/O lines. Six pins are dedicated as general- purpose I/O pins. Other I/O lines are multiplexed with an external signal of a peripheral to optimize the use of available package pins ...

... PDC, and a Time-guard register, used when interfac- ing with slow remote equipment. The AT91FR40161 features a Timer Counter block that includes three identical 16-bit timer counter channels. Each channel can be independently programmed to perform a wide range of functions including frequency measurement, event counting, interval mea- surement, pulse generation, delay timing and pulse width modulation ...
