full-speed PHY and ULPI interface to external high-speed PHY.
USB interface electrical test software included in ROM USB stack.
One 550 UART with DMA support and full modem interface.
Three 550 USARTs with DMA and synchronous mode support and a smart card
interface conforming to ISO7816 specification. One USART with IrDA interface.
Two C_CAN 2.0B controllers with one channel each.
Two SSP controllers with FIFO and multi-protocol support. Both SSPs with DMA
One SPI controller.
One Fast-mode Plus I2C-bus interface with monitor mode and with open-drain I/O
pins conforming to the full I2C-bus specification. Supports data rates of up to
One standard I2C-bus interface with monitor mode and with standard I/O pins.
Two I2S interfaces, each with DMA support and with one input and one output.
External Memory Controller (EMC) supporting external SRAM, ROM, NOR flash,
and SDRAM devices.
LCD controller with DMA support and a programmable display resolution of up to
1024 H 768 V. Supports monochrome and color STN panels and TFT color
panels; supports 1/2/4/8 bpp Color Look-Up Table (CLUT) and 16/24-bit direct pixel
mapping. Available on parts LPC4357/53 only.
Secure Digital Input Output (SD/MMC) card interface.
Eight-channel General-Purpose DMA (GPDMA) controller can access all memories
on the AHB and all DMA-capable AHB slaves.
Up to 164 General-Purpose Input/Output (GPIO) pins with configurable
