Functional replacement for LPC23xx and 24xx family devices.
System:
ARM Cortex-M3 processor, running at frequencies of up to 120 MHz. A Memory
Protection Unit (MPU) supporting eight regions is included.
ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
Mult AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, and General Purpose DMA controller. This
interconnect provides communication with no arbitration delays unless two masters
attempt to access the same slave at the same time.
Split APB bus allows for higher throughput with fewer stalls between the CPU and
DMA. A single level of write buffering allows the CPU to continue without waiting for
completion of APB writes if the APB was not already busy
Cortex-M3 system tick timer, including an external clock input option.
Standard JTAG test/debug interface as well as Serial Wire Debug and Serial
WireTrace Port options.
Emulation trace module supports real-time trace.
Boundary scan for simplified board testing.
Non-maskable Interrupt (NMI) input.
Memory:
512 kB on-chip flash program memory with In-System Programming (ISP) and
In-Application Programming (IAP) capabilities. The combination of an enhanced
flash memory accelerator and location of the flash memory on the CPU local
code/data bus provides high code performance from flash.
96 kB on-chip SRAM includes:
64 kB of SRAM on the CPU with local code/data bus for high-performance CPU
access.
Two 16 kB SRAM blocks with separate access paths for higher throughput. These
SRAM blocks may be used for DMA memory as well as for general purpose
instruction and data storage.
4032 byte on-chip EEPROM.
LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film
Transistors (TFT) displays.
Dedicated DMA controller.
Selectable display resolution (up to 1024
768 pixels).
Supports up to 24-bit true-color mode.
External Memory Controller (EMC) provides support for asynchronous static memory
devices such as RAM, ROM and flash, as well as dynamic memories such as single
data rate SDRAM.
Eight channel General Purpose DMA controller (GPDMA) on the AHB mult
matrix that can be used with the SSP, I2S, UART, CRC engine, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, GPIO, and for
memory-to-memory transfers.
Serial interfaces:
Ethernet MAC with MII/RMII interface and associated DMA controller. These
functions reside on an independent AHB.
USB 2.0 full-speed dual port device/host/OTG controller with on-chip PHY and
associated DMA controller.
Five UARTs with fractional baud rate generation, internal FIFO, DMA support, and
RS-485/EIA-485 support. One UART (UART1) has full modem control I/O, and one
UART (USART4) supports IrDA, synchronous mode, and a smart card mode
conforming to ISO7816-3.
Three SSP controllers with FIFO and multi-protocol capabilities. The SSP
interfaces can be used with the GPDMA controlle
