HME - M7-Products Center

HME-M7 family FPGA is integrated with the ARM Cortex™-M3 32-bit RISC core, high performance FPGA, and plenty of peripherals. This high-performance core works at 300 MHz frequency, with a Memory Protection Unit (MPU) and high-speed embedded memories (Code RAM memory up to 128 Kbytes with 8K code cache and data RAM up to 64 Kbytes). Also, HME-M7 fulfills customized system design and IP using the programmable logic resources, embedded RAM blocks and DSPs.

The device offers dual 12-bit 1MSPS ADC, four general-purpose 32-bit timers which can be used as time bases. Moreover, it contains standard and advanced communication interfaces: I2Cs and SPIs, USARTs, ethernet, dual CAN and a USB, as well as include a real-time clock.

The 16bit DDR2/3 hard controller can meet the large and high-speed data memory with access requirements. The AHB bus is used to connect the FPGA, ARM core and the peripherals. A high-performance internal AHB system bus interconnects the embedded processor, its peripherals, and the FPGA at a maximum speed of 300MHz.

The bus simultaneously provides 32 bits of read data, 32 bits of write data, and a 32-bit address. Multiple bus masters arbitrate for bus access. Potential bus masters include the ARM Cortex™-M3 processor, the read and write channels of each DMA channel, the JTAG interface, and FPGA fabric.
