... RISC architecture with a high-density 16-bit instruction set and very low power consumption. The AT91FR4042 ARM microcontroller features 2 Mbits of on-chip SRAM and 4 Mbits of Flash memory in a single compact 121-ball BGA package. Its high level of integra- tion and very small footprint make the device ideal for space-constrained applications. ...

... Flash. The AT91 Flash Uploader software is able to upload program application software into its Flash memory. The AT91FR4042 integrates several peripherals, which 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 ...

... Peripheral Data Controller (PDC) channels. The 3-channel, 16-bit Timer Counter (TC) is highly programmable and supports capture or waveform modes. Each TC channel can be programmed to measure or generate dif- ferent kinds of waves, and can detect and control two input/output signals. The TC has also 3 external clock signals. AT91FR4042 7 ...

... Being able to dynamically update application software in the 256-Kbyte SRAM adds an extra dimension to the AT91FR4042. The AT91FR4042 also integrates a 4-Mbit Flash memory that is accessed via the Exter- nal Bus Interface. All data, address and control lines, except for the Chip Select signal, are connected within the device ...

... The ARM vectors (Reset, Abort, Data Abort, Prefetch Abort, Undefined Instruction, Interrupt, Fast Interrupt) are mapped from address 0x0 to address 0x20. In order to allow these vectors to be redefined dynamically by the software, the AT91FR4042 uses a remap command that enables switching between the boot memory and the internal primary SRAM bank addresses ...

... AT91FR4042 12 During boot, the EBI must be configured with correct number of standard wait states example, five standard wait states are required when the microcontroller is running at 66 MHz. The user must ensure that all VDDIO, VDDCORE and all GND pins are connected to their respective supplies by the shortest route. The Flash memory powers-on in read mode ...

... Note that in the event that the Flash Uploader is erased from the first sector while the new final application is not yet programmed, and while the target system power supply is switched off, it leads to a non-recoverable error and the AT91FR4042 cannot be re- programmed by using the Flash Uploader. ...

... Peripheral Data Controller 2648D–ATARM–03/04 The AT91FR4042 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 AT91FR4042 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 AT91FR4042 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 ...
