1. Overview
MINI-MAX/ARM-C and MINI-MAX/ARM-E are general purpose, low-cost, highly-reliable and highly-
expandable micro-controller systems, based on Philips LPC213x 32/16 bit ARM7TDMI-S CPU with real-
time emulation and embedded trace support. MINI-MAX/ARM-E provides 10-TBASE Ethernet port.
CPU features.
•
16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
•
8/16/32 KB of on-chip static RAM and 32/64/128/256/512 KB of on-chip Flash program
memory. 128 bit wide interface/accelerator enables high speed 60 MHz operation.
•
In-System/In-Application Programming (ISP/IAP) via on-chip boot-loader software.
Single Flash sector or full chip erase in 400 ms and programming of 256 bytes in 1 ms.
•
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.
•
One (LPC2131/32) or two (LPC2134/36/38) 8 channel 10-bit A/D converters provides
a total of up to 16 analog inputs, with conversion times as low as 2.44 ms per channel.
•
Single 10-bit D/A converter provides variable analog output (LPC2132/34/36/38).
•
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 UART’s (16C550), two Fast I2C-bus (400 kbit/s),
SPI and SSP with buffering and variable data length capabilities.
•
Vectored interrupt controller with configurable priorities and vector addresses.
•
Up to 47 5 V tolerant general purpose I/O pins in tiny LQFP64 package.
•
Up to nine edge or level sensitive external interrupt pins available.
•
60 MHz maximum CPU clock available from programmable on-chip PLL with settling
time of 100 ms.
•
On-chip integrated oscillator operates with external crystal in range of 1 MHz to 30 MHz
and with external oscillator up to 60 MHz.
•
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.
•
Processor wake-up from Power-down mode via external interrupt or BOD.
•
Single power supply chip with POR and BOD circuits:
•
CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5V tolerant I/O pins.
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 (MINI-MAX/ARM-E only).
•
8 Mbit serial FLASH memory
•
Two RS232 Serial Ports
•
Second CPU, 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 circuits.
•
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, which allows Real Time Clock unit to operate in the
absence of external power.
