Product details
Overview
AT91SAM9G10-CU-999 from Microchip Technology is an ARM926EJ-S-based embedded microprocessor unit (MPU) optimized for LCD-display host applications. It delivers 293 MIPS at 266 MHz, integrates 32 KB ROM and 16 KB SRAM with single-cycle access, supports SDRAM/NAND/CompactFlash via its External Bus Interface (EBI), and features dual USB 2.0 Full Speed ports (host and device) with OHCI compliance.
For engineers reviewing the AT91SAM9G10-CU-999 datasheet, AT91SAM9G10-CU-999 pinout, AT91SAM9G10-CU-999 application, or AT91SAM9G10-CU-999 equivalent, key selection criteria include its 217-ball LFBGA package, 1.08–1.32 V core supply, integrated LCD controller supporting up to 16M-color TFT displays, and full JTAG boundary scan for debug and production test.
Technical Context
The AT91SAM9G10-CU-999 implements a five-stage pipelined ARM926EJ-S core with MMU, 16 KB instruction and 16 KB data caches, and write buffer - enabling deterministic real-time execution. Its bus matrix handles five AHB masters (ARM core, USB host, LCD controller, PDC, EBI) and five slaves, supporting remappable boot memory and dynamic arbitration modes including round-robin with burst breaking.
System-level control is centralized in the System Controller (SYSC), integrating clock generation (dual PLLs + 32.768 kHz oscillator), power management (software-programmable low-power modes), advanced interrupt controller (8-level priority, vectored), watchdog timer (key-protected, windowed), and three 32-bit PIO controllers managing 96 I/O lines with Schmitt-trigger inputs and programmable pull-ups.
