New Micros Inc. (NMI) NMIT-0021 F68HC11 target computer

100 mm by 160 mm Eurocard board without 68HC24 Port Expander

About 4 inches by 6 inches

The NMIT-0021 is the F68HC11-based CPU board for the NMI "100 Squared"[tm] board series.

FEATURES:

• F68HC11[tm] CPU
• Max-FORTH[tm] built-in programming language
• 231 predefined words in the language
• 3 parallel ports
• 1 Asynchronous Serial Ch. RS-232
• 1 Synchronous Serial Channel, TTL
• 8-channel, 8-bit A/D
• 8-bit counter
• 16-bit timer
• 3 input captures
• 5 output compares
• 1/2K EEPROM
• 8K RAM
• 64K address space
• Three 28-pin JEDEC memory sockets
• Flexible address decoding, socket assignments
• Battery backup circuits for memory

The NMIT-0021 is a complete system, ready to develop, or run, dedicated applications. Simply apply regulated 5V power, attach a host RS-232 port, and begin programming. Then, the user program can be added to its internal EEPROM, or externally battery-backed RAM, or by a user-supplied ROM/EPROM/EEPROM.

All circuit paths of the more expensive NMIX-0021 are provided on the PCB, but are not populated. The user may add parts as desired

The "100 Squared"[tm] were named for their size, with 100x100mm of active component area, on a 100x160mm Eurocard format. The system is compatible with the New Micros NMIX, NMIT and NMIS series peripherals with a VSC-34 connector added. The 28-pin JEDEC memory sockets can accept various memory devices. Default wiring is for 8 K devices.

Smart terminals, or personal computers with communications packages, can download source code to the NMIT-0021 via RS-232 ports. Interactive code development on the target system gives fast and efficient debugging. The built-in language gives machine level access.

The NMIT-0021 makes a very cost effective solution as target systems particularly when small size, CMOS low power, and ease of development are required. Few single board computer offers so many features in such a small space. High Level Language support offers resident FORTH, and optionally BASIC and Assembly Language. FORTH and C cross compilers and cross assemblers are also available.
