The ultimate Internet-ready 32-bit microcontroller board at a truly low cost
BiPOM Electronics is a proud ATMEL Consultant for ARM ( SAM7, SAM9 and AT91RM9200 ) Family of microcontrollers.
CPU features:
16/32-bit ARM7TDMI-S LPC2138 microcontroller from NXP (Philips) in a tiny LQFP64 package.
32 KB static RAM (on LPC2138) and 512 KB Flash program memory (on LPC2138). 128 bit wide interface/accelerator enables high speed 60 MHz operation.
In-System/In-Application Programming (ISP/IAP) via on-chip boot-loader software.
Embedded ICE RT and Embedded Trace interfaces offer real-time debugging with the on-chip Real Monitor software and high speed tracing of instruction execution.
16-channel 10-bit A/D converter provides a total of up to 16 analog inputs, with conversion times as low as 2.44 ms per channel.
10-bit D/A converter provides variable analog output.
Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.
Low power Real-time clock with independent power and dedicated 32 kHz clock input.
Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s), SPI and SSP.
Vectored interrupt controller with configurable priorities and vector addresses.
Up to 47 5V-tolerant general purpose I/O pins.
Up to 9 edge-sensitive or level-sensitive external interrupt pins available.
Power saving modes include Idle and Power-down.
Individual enable/disable of peripheral functions as well as peripheral clock scaling down for additional power optimization.
Single power supply chip with Power On Reset (POR) and Brown Out Detect (BOD) circuits.
MINI-MAX/ARM boards complement these features, providing:
14.7456 MHz crystal to achieve 58.9824 MHz core
Microchip ENC28J60 Ethernet controller with network interface.
8 Mbit serial FLASH memory (ATMEL DataFlash)
Two RS232 Serial Port Headers
Second CPU (ATMEL AVR ATTiny), allowing In-circuit Programming of main CPU through the serial port
JTAG programming interface
Keypad connector
LCD connector ( programmable contrast adjustment for the LCD )
Screw terminal block for analog inputs.
Expansion bus interface to low-cost peripheral boards
Separate power supplies for 5V and 3.3V, digital and analog circuits.
32 KHz crystal and a 3 Volt lithium battery (optional), which allows Real Time Clock unit to operate in the absence of external power.
6 Volts DC Adapter, serial cable, serial downloader, printed technical manual and schematics included.
(The adapter is 110VAC type. Please let us know if you would like to receive a 220VAC adapter for your country or if you would like to have the board shipped without an adapter.)
