Description The MC2000-332 is a high performance, low power single board computer. Initial program execution begins in 8 bit wide boot ROM. Execution can be transferred to 16 bit wide flash memory for faster execution or 16 bit wide no wait state battery backable RAM for maximum performance. The integral TPU supports special time related functions such as PWM generation, quadrature decoding, asynchronous serial transfer, pulse generation, input time stamp capture and period measurement. Any TPU channel can generate an interrupt on positive or negative input transitions. 8 A/D, 12 DIO, 10 TPU channels and 7 interrupts are available. VAST network and one reconfigurable asynchronous serial channel support off board peripherals. Development Environment This board can be programmed in Vesta Multi-Tasking Basic, C/C++, or Assembly language. The development kit for this board contains our MC-2000-332 Development Platform (part number Z12) that attaches to the MC2000-332 and provides all the ports for development purposes. Specs

Connectors on the DEV-332 The connectors for the power, battery, COM, COM/TTL, DEV, BDM, ADIO, LCD, Keypad, and VAST network, are provided via the DEV-332 interconnection development platform.

ADIO Connector

The ADIO connector allows convenient access to all of the MC2000-332 analog and digital inputs and outputs.

Power Connector The power connector supplies primary power at ground and +5. Standby power to the RTC and RAM is supplied via pin 4. The Vesta PWRPROTO peripheral AC connector contains a

super cap that can store power to keep the MC2000-332 RAM and RTC alive for about 12 hours. The PWRON* signal allows the MC2000-332 to switch its own main power on and off

if a self-switching supply is installed. PWRON* will go low to turn on an external power supply.

Battery Backup Connector The battery backup connector provides standby power to RAM in case power from the Power Connector is lost for long periods. The external battery is isolated from the +5 supply via a diode network. Standby power is 3.5V < standby power (Vstby) <5.0V. Pin 2 will provide a small trickle that may be selected to charge an external battery. A .1F supercap battery across pins 1 (-) and 2 (+) will keep the MC2000-332 RAM and RTC alive for about 12 hours.

Dev Connector The Development connector supplies RS-232 level signals at up to 19.2k Baud from a software UART supported by the TPU.

COM Connector The Communications connector supplies RS-232 signals at up to 115k Baud directly from the integral CPU UART.

COM/TTL Connector This connector allows access to the TTL level signals going to the integral CPU UART. Note that there is only one UART and by using this connector, you are effectively disabling the RS-232 COM connector described above. Normally, pins 1 and 2 of this connector are shorted together to activate RS-232 levels on the "COM" connector. This port is used primarily to buffer the serial port for RS-485 networks. The signal T/R* is supported by Vesta Basic and the Vesta C Library as a transmitter control function on a multidrop network.

BDM Connector The Background Debugger Mode connector allows debugging during C development.

VAST Connector The Vesta Addressable Synchronous Transfer connector allows synchronous serial bus expansion to VAST peripherals. The Schottky diodes and RC filtering of the MISO signal is optimized for 100 kHz SCK and remote (up to 100') VAST peripherals. If you want to run local SPI peripherals at higher clock speeds, these components must be modified. Most IIC peripherals do not support clock rates higher than 100 kHz.

LCD Connector The LCD is interfaced in the "4-bit" mode. The LCD contrast voltage, Vo, can be adjusted using the onboard trimpot for any voltage between +5 and ground.

Keypad Connector The keypad is a standard 4 x 4 matrix type. Maximum resistance is 200 ohms. The 8 x 470 ohm resistor network isolates the keypad from the LCD.
