Page 6: Ethernet Controller
Micro-controller The LPC2131/2132/2134/2136/2138 micro-controllers are based on a 32/16 bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the micro-controller with 32/ 64/128/ 256/ 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 maximum clock rate. - Page 7 Keypad connector Keypad connector can be used to scan various types of keypads, such as 3 by 5 or 4 by 4. Keypad connector contains 5 Volt power and ground lines and the 8 port lines of the micro-controller. The lines can also be used as general-purpose inputs/outputs.
- Page 8 LCD Connector LCD connector serves various types of character and graphic LCD modules. Alternatively LCD port can be used as a 6-bit general purpose I/O. Contrast is a 10-bit analog PWM output to adjust the contrast of the LCD display under software control. Alternatively it can be used as a general purpose analog output.
- Page 9 RS232 Serial Ports Two RS232 serial ports are available on the MINI-MAX/ARM. IC4 converts micro-controller’s RXD and TXD pins to/from RS232 levels. IC4 has an internal circuit that generates +/- 10 Volts for RS232 logic levels. First RS232 port is wired to a 10-pin header (J4). Second RS232 port is wired to a 6-pin header (J5). There are two options.

- Page 11 Expansion connector Expansion connector can be used for interfacing to external circuitry, prototyping boards and peripheral boards. Expansion connector has 16 lines, which can be used as general purpose I/O. Some of these lines have special functions. MINI-MAX/ARM peripheral boards can be connected either as a piggy-back daughter-board on MINI-MAX/ARM using standoffs or can be placed up away from MINI-MAX/ARM using a 20-wire ribbon cable.
- Page 12 Analog interface Analog terminal J8 serves for interfacing to various types of analog periphery, such as strain gages, pressure sensors, thermocouples etc. Five ADC inputs, analog reference VREF, analog power supply VAN and analog ground are wired to J8. Analog terminals (J8) Signal P0.27 (AN0) P0.28 (AN1)

Page 13: Real Time Clock
Real Time Clock The Real Time Clock (RTC) is a set of counters for measuring time when system power is on, and when it is off. It uses little power in power down mode. LPC213x RTC provides Seconds, Minutes, Hours, Day of Month, Month, Year, Day of Week, and Day of Year. On the Mini-Max/ARM, the RTC can be clocked by an external 32.768 KHz oscillator, or by a programmable divider based on the peripheral clock. -
Page 14: Peripherals
4. Peripherals A peripheral board can either be stacked on top of MINI-MAX/ARM using stand-offs or connected in a chain configuration using flat ribbon cable. Figure 8 shows how any peripheral board can be connected to a micro-computer board in a stacked fashion. Figure 9 shows the chain connection.
