Description
The LPC2364/65/66/67/68 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation that combines the microcontroller with up to 512 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical performance in interrupt service routines and DSP algorithms, this increases performance up to 30 % over Thumb mode. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. The LPC2364/65/66/67/68 are ideal for multi-purpose serial communication applications. They incorporate a 10/100 Ethernet Media Access Controller (MAC), USB full speed device with 4 kB of endpoint RAM (LPC2364/66/68 only), four UARTs, two CAN channels (LPC2364/66/68 only), an SPI interface, two Synchronous Serial Ports (SSP), three I 2C-bus interfaces, and an I2S-bus interface. This blend of serial communications interfaces combined with an on-chip 4 MHz internal oscillator, SRAM of up to 32 kB, 16 kB SRAM for Ethernet, 8 kB SRAM for USB and general purpose use, together with 2 kB battery powered SRAM make these devices very well suited for communication gateways and protocol converters. Various 32-bit timers, an improved 10-bit ADC, 10-bit DAC, one PWM unit, a CAN control unit (LPC2364/66/68 only), and up to 70 fast GPIO lines with up to 12 edge or level sensitive external interrupt pins make these microcontrollers particularly suitable for industrial control and medical systems.
