LPC3220 Description
The LPC3220/30/40/50 embedded microcontrollers were designed for low power, high performance applications. NXP achieved their performance goals using a 90 nanometer process to implement an ARM926EJ-S CPU core with a vector floating point co-processor and a large set of standard peripherals including USB On-The-Go. The LPC3220/30/40/50 operates at CPU frequencies of up to 266 MHz.
LPC3220 Key Features
- ARM926EJ-S processor, running at CPU clock speeds up to 266 MHz
- Vector Floating Point (VFP) coprocessor
- 32 kB instruction cache and 32 kB data cache
- Up to 256 kB of Internal SRAM (IRAM)
- Selectable boot-up from various external devices: NAND flash, SPI memory, USB
- Multi-layer AHB system that provides a separate bus for each AHB master, including both an instruction and data bus for
- External memory controller for DDR and SDR SDRAM as well as for static devices
