Introduction
1–5
ISO 9001 Manufacturing. Ampro is a certified ISO 9001 vendor.
Regulatory testing. Knowing that many embedded systems must qualify under EMC emissions
susceptibility testing, Ampro designs boards with careful attention to EMI issues. Boards are tested in
standard enclosures to ensure that they can pass such emissions tests. Tests include European Union
Directives EMC EN55022 and EN55011, ESD EN 61000-4-2, RF susceptibility ENV 50140, EFT EN61000-
4-5, and conducted emissions at US voltages per FCC Part 15, Subpart J.
Wide-range temperature testing. Ampro Engineering qualifies all of its designs by extensive thermal and
voltage margin testing.
3.3V or 3.1V Voltage Reduction Technology (VRT) CPU for greater high temperature tolerance. The
board uses the latest low-voltage CPU technology to extend its temperature range and reduce cooling
requirements.
Shock and Vibration Testing. Boards intended for use in harsh environments are tested for shock and
vibration durability to MIL-STD 202F, Method 213-I, Condition A (three 50G shocks in each axis) and MIL-
STD 202F, Method 214A, Table 214-I, Condition D (11.95B random vibration, 100 Hz to 1000 Hz). (Contact
your Ampro sales representative to obtain Shock and Random Vibration Test Report for the Little Board/P5i
CPU for details.)
1.3 SOFTWARE
The vast array of commercial and public-domain software for the IBM PC and PC/AT is usable in Little
Board/P5i-based systems. You can use the most popular software development tools (editors, compilers,
debuggers, etc.) for developing code for your application. With this software and the standard Ampro-
supplied utilities and drivers, you can quickly tailor a system to your needs.
Use the board’s SETUP function for all system configuration. SETUP can be invoked using the DEL key at
boot time or from the DOS command line using a utility program, SETUP.COM, available on the Common
Utilities diskette.
SETUP information is stored in both the battery-backed CMOS RAM-portion of the real-time clock, and in a
configuration EEPROM. For a complete discussion of SETUP, see Chapter 3.
1.4 DESIGNING LITTLE BOARD SYSTEMS
The Little Board/5Pi CPU affords a great deal of flexibility in system design. You can build a system using
only the Little Board, serial or parallel devices for input/output, and a Solid State Disk drive in the byte-wide
socket.
Self-stacking Modules. The simplest way to expand a Little Board system is with self-stacking Ampro
MiniModules. MiniModules are available for a wide variety of functions. You can stack the MiniModules on
the Little Board and avoid the need for bus cables, card cages, and backplanes.
MiniModules mount directly on the ISA portion of the PC/104-Plus bus connector. Modules can be stacked
with an inter-board spacing of ~0.66 inches. Thus, a 3-module system fits within the outline of the Little
Board and within a 2.4 inch vertical space. A complete description of self-stacking options with various
Ampro MiniModules and other PC/104-compatible modules can be found in Ampro Application Note AAN-
9402, available from Ampro.
