AT94K10AL-25BQU

The AT94K10AL-25BQU is a monolithic Field Programmable System Level Integrated Circuit (FPSLIC) from Microchip Technology that integrates an AT40K SRAM-based FPGA with an embedded high-performance RISC AVR microcontroller core. The FPGA provides 10,000 gates, 576 core cells, 846 registers, and 4 Kbit of distributed single/dual port user SRAM. The AVR core is an 8-bit architecture with 120+ instructions, a hardware multiplier, and operates at up to 25 MHz, delivering near 1 MIPS per MHz.

The device includes up to 36 Kbytes of dynamically allocated instruction and data SRAM (20K-32K bytes program, 4K-16K bytes data). It features industry-standard interfaces including I²C and two programmable UARTs, as well as a JTAG interface (IEEE 1149.1 compliant) for extensive on-chip debug support. The FPGA supports dynamic reconfiguration and cache logic designs, with 16 decoded AVR address lines directly accessible to the FPGA for custom peripheral integration.

The AT94K10AL-25BQU is supplied in a 144-LQFP package (20x20 mm) with surface mount mounting. It operates over a supply voltage range of 3V to 3.6V and a temperature range of -40°C to 85°C. The I/O pins are 5V tolerant. The device features very low static and dynamic power consumption, with typical standby current of 100 µA and active current of 2-3 mA per MHz, making it suitable for portable and handheld applications.
