1. General description
The LPC2921/2923/2925 combine an ARM968E-S CPU core with two integrated TCM
blocks operating at frequencies of up to 125 MHz, Full-speed USB 2.0 device controller,
CAN and LIN, up to 40 kB SRAM, up to 512 kB flash memory, two 10-bit ADCs, and
multiple serial and parallel interfaces in a single chip targeted at consumer, industrial, and
communication markets. To optimize system power consumption, the
LPC2921/2923/2925 has a very flexible Clock Generation Unit (CGU) that provides
dynamic clock gating and scaling.
2. Features and benefits
ARM968E-S processor running at frequencies of up to 125 MHz maximum.
Multilayer AHB system bus at 125 MHz with four separate layers.
On-chip memory:
Two Tightly Coupled Memories (TCM), 16 kB Instruction (ITCM) and 16 kB Data
TCM (DTCM).
On the LPC2925, two separate internal Static RAM (SRAM) instances, 16 kB each.
On the LPC2923 and LPC2921, one 16 kB SRAM block.
8 kB ETB SRAM, also usable for code execution and data.
Up to 512 kB high-speed flash-program memory.
16 kB true EEPROM, byte-erasable/programmable.
Dual-master, eight-channel GPDMA controller on the AHB multilayer matrix which can
be used with the
Serial Peripheral Interface (SPI)
interfaces and the UARTs, as well as
for memory-to-memory transfers including the TCM memories.
Serial interfaces:
USB 2.0 full-speed device controller with dedicated DMA controller and on-chip
device PHY.
Two-channel CAN controller supporting FullCAN and extensive message filtering.
Two LIN master controllers with full hardware support for LIN communication. The
LIN interface can be configured as UART to provide two additional UART
interfaces.
Two 550 UARTs with 16-byte Tx and Rx FIFO depths, DMA support, and
RS-485/EIA-485 (9-bit) support.
Three full-duplex Q-SPIs with four slave-select lines; 16 bits wide; 8 locations deep;
Tx FIFO and Rx FIFO.
Two I
2
C-bus interfaces.
