LPC2300 series of ARM7-based microcontrollers

Semiconductor Vendor with ARM Processor RTL license from ARM

Product Description

The LPC23xx microcontroller series from NXP uses a high-performance 32-bit ARM7 core that operates at up to 72 MHz. Each device has up to 512 KB of on-chip Flash and up to 98 KB of on-chip SRAM memory. Each LPC23xx device features two AHB buses, so high-bandwidth peripherals like Ethernet and USB can run simultaneously, without impacting the main application.

In-System Programming (ISP) and In-Application Programming (IAP) software minimize programming time – each 256-byte line takes only 1 ms to program, and a single-sector or full-chip erase takes only 400 ms. A 128-bitwide memory interface and a patented memory accelerator enable 32-bit code execution from Flash with zero waitstates. For applications where code size is critical, an alternative 16-bit Thumb mode reduces code by more than 30% with minimal performance penalties.

Each microcontroller is equipped with a 10/100 Ethernet MAC interface, a USB 2.0 full-speed (12 Mbps) device, USB 2.0 full speed Open Host Control Interface / On-The-Go, two CAN 2.0B channels, a general-purpose DMA controller, a 10-bit A/D converter and a 10-bit D/A converter. The Ethernet MAC has 16 KB of SRAM and an associated DMA controller on an independent AHB bus. The USB controller has 4 KB of USB SRAM and accessible DMA, and supports Control, Interrupt, Bulk, and Isochronous data-transfer modes with 32 endpoints.

Multiple serial communications interfaces increase design flexibility, provide larger buffer size, and deliver higher processing power. There are four 16C550 UARTs (one with IrDA), three I2C-bus interfaces, three SPI/SSP interfaces, an I2S interface, and an interface for SD/MMC memory cards. There are four 32-bit capture/compare timers, a PWM unit, a low-power real-time clock with 2 KB of battery-backed SRAM, a Watchdog timer, and a 4-MHz internal RC oscillator that can be used as the main system clock.

An independent clock divider for each peripheral lets the designer minimize power consumption. Also, each pin of Port 0 and Port 2 can be used as an external interrupt. There are up to 104 general-purpose I/O lines that toggle at rates up to 36 MHz. The operating temperature range for all the devices is -40 to 85 °C. The LPC2378 and LPC2388 feature an 8-bit MultiPort Memory Controller (MiniBus) that supports asynchronous RAM, ROM, and Flash. The MiniBus can also be used to interface off-chip memory-mapped devices and peripherals.

For debugging, each device supports real-time emulation and embedded trace support and has an integrated vectored interrupt controller (VIC). Also, for compatibility with existing tools, each device uses the standard ARM test/debug JTAG interface.
