Single-chip 16-bit/32-bit micro; 512 kB ﬂash, Ethernet, CAN,

ISP/IAP, USB 2.0 device/host/OTG, external memory interface

Rev. 02 — 25 November 2008

Product data sheet

1. General description

NXP Semiconductors designed the LPC2458 microcontroller around a 16-bit/32-bit

ARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG and

embedded trace. The LPC2458 has 512 kB of on-chip high-speed ﬂash memory. This

ﬂash memory includes a special 128-bit wide memory interface and accelerator

architecture that enables the CPU to execute sequential instructions from ﬂash memory at

the maximum 72 MHz system clock rate. This feature is available only on the LPC2000

ARM microcontroller family of products. The LPC2458 can execute both 32-bit ARM and

16-bit Thumb instructions. Support for the two instruction sets means engineers can

choose to optimize their application for either performance or code size at the sub-routine

level. When the core executes instructions in Thumb state it can reduce code size by more

than 30 % with only a small loss in performance while executing instructions in ARM state

maximizes core performance.

The LPC2458 microcontroller is ideal for multi-purpose communication applications. It

incorporates a 10/100 Ethernet Media Access Controller (MAC), a USB full-speed

Device/Host/OTG Controller with 4 kB of endpoint RAM, four UARTs, two Controller Area

Network (CAN) channels, an SPI interface, two Synchronous Serial Ports (SSP), three I²C

interfaces, and an I²S interface. Supporting this collection of serial communications

interfaces are the following feature components; an on-chip 4 MHz internal precision

oscillator, 98 kB of total RAM consisting of 64 kB of local SRAM, 16 kB SRAM for

Ethernet, 16 kB SRAM for general purpose DMA, 2 kB of battery powered SRAM, and an

External Memory Controller (EMC). These features make this device optimally suited for

communication gateways and protocol converters. Complementing the many serial

communication controllers, versatile clocking capabilities, and memory features are

various 32-bit timers, an improved 10-bit ADC, 10-bit DAC, two PWM units, four external

interrupt pins, and up to 136 fast GPIO lines. The LPC2458 connects 64 of the GPIO pins

to the hardware based Vector Interrupt Controller (VIC) that means these external inputs

can generate edge-triggered interrupts. All of these features make the LPC2458

particularly suitable for industrial control and medical systems.

2. Features

I ARM7TDMI-S processor, running at up to 72 MHz.

I 512 kB on-chip ﬂash program memory with In-System Programming (ISP) and

In-Application Programming (IAP) capabilities. Flash program memory is on the ARM

local bus for high performance CPU access.

I 98 kB on-chip SRAM includes:

N 64 kB of SRAM on the ARM local bus for high performance CPU access.

N 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
