LPC214X

60-MHz, 32-bit microcontroller with ARM7TDMI-S™ core LPC214x ARM7-based microcontrollers with full-speed USB 2.0 These powerful yet cost-effective microcontrollers offer USB 2.0 full-speed (12 Mbps) capability and have up to 512 KB of ISP/IAP Flash and up to 40 KB of SRAM. Each has up to two 10-bit A/D converters, a 10-bit D/A converter, two I2C-bus interfaces, and Fast I/O.

Each device has up to 512 KB of on-chip Flash and up to 40 KB of on-chip SRAM memory. In-System Programming (ISP) and InApplication Programming (IAP) software minimize programming time – each 256byte line takes only 1 ms to program, and a single-sector or full-chip erase takes only 400 ms. A 128-bit-wide memory interface and a patented memory accelerator enable 32-bit code execution from Flash with zero wait-states. 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 in the family includes a USB 2.0 full-speed (12 Mbps) device that supports 32 endpoints with 2 KB of endpoint RAM. In the LPC2146 and the LPC2148, up to 8 KB of the RAM can be used by the USB DMA. In all the devices, the USB function supports Control, Interrupt, Bulk, and Isochronous data-transfer modes. Designers can choose between GoodLink™ and SoftConnect™ functionality. Each microcontroller is also equipped with up to two 10-bit A/D converters and a 10-bit D/A converter. Multiple serial communications interfaces increase design flexibility, provide larger buffer size, and deliver higher processing power. There are two 16C550 UARTs, two Fast I2C-bus (400 kbps) interfaces, and two SPI interfaces (one with capabilities for buffering and variable data length). There are two 32-bit timers (each with four capture and compare channels), a PWM unit with six outputs, a real-time clock, and a Watchdog timer. 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. Other features include 45 Fast I/O pins (5-V tolerant) with switching up to 15 MHz, and an operating temperature range of -40 to 85 °C.
