Product Summary

The LPC2478FBD208 is a Single-chip 16-bit/32-bit microcontroller, powered by the ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of applications that require advanced communications and high quality graphic displays. The LPC2478FBD208 microcontroller 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 LPC2478FBD208, with real-time debug interfaces that include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb instructions. Applications include: Industrial control, Medical systems, Portable electronics, Point-of-Sale (POS) equipment.

Parametrics

LPC2478FBD208 absolute maximum ratings: (1)supply voltage (3.3 V): 3.0 to 3.6 V; (2)DC-to-DC converter supply voltage: 3.0 to 3.6 V; (3)analog 3.3 V pad supply voltage: -0.5 +4.6 V; (4)input voltage on pin VBAT for the RTC: -0.5 +4.6 V; (5)input voltage on pin VREF: -0.5 +4.6 V; (6)analog input voltage on ADC related pins: -0.5 +5.1 V.

Features

LPC2478FBD208 features: (1)LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film Transistors (TFT) displays; (2)Dual Advanced High-performance Bus (AHB) system allows simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no contention; (3)Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts; (4)Single 3.3 V power supply (3.0 V to 3.6 V); (5)4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as the system clock; (6)Three reduced power modes: idle, sleep, and power-down; (7)Four external interrupt inputs configurable as edge/level sensitive. All pins on PORT0 and PORT2 can be used as edge sensitive interrupt sources; (8)Brownout detect with separate thresholds for interrupt and forced reset; (9)On-chip power-on reset; (10)On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz; (11)On-chip PLL allows CPU operation up to the maximum CPU rate without the need for a high frequency crystal. May be run from the main oscillator, the internal RC oscillator, or the RTC oscillator; (12)Boundary scan for simplified board testing; (13)Versatile pin function selections allow more possibilities for using on-chip peripheral functions; (14)Standard ARM test/debug interface for compatibility with existing tools; (15)Emulation trace module supports real-time trace.
