SBC Module Description

The microMODUL-8051/Low Power combines PHYTEC's matchbox-size 8051 compatible microMODUL with minimum power requirements. With its 11-channel, 12-bit A/D converter and various low power modes, the board is particularly well-suited for data acquisition and processing over longer time horizons. The low power microMODUL-8051 is populated with the Dallas DS80C323 controller. This device offers power-saving functions. This device offers power-saving functions. In Sleep-Mode Vcc is suspended and such important on-board components as memory, RTC and wake-up logic are supplied via a battery buffer. In Power-Down mode only the controller is suspended. Idle-Mode provides the smallest power savings yet offers a very quick latent reaction time. The standard memory configuration of the board features 32 (up to 512) KB SRAM and 256 (up to 512 or as low as 32) KB Flash for storage of user code. Free Chip-Select signals enable connectivity to external periperals. The module communicates by means of an RS-232 transceiver.
