Product details
Overview
ST72325-D/RAIS from Raisonance is a standalone interchangeable daughterboard featuring the ST72F325AR9 8-bit microcontroller in LQFP64 package, supporting ST72324/ST72325 MCU variants with on-chip Flash, ADC, SPI, I²C, and timer peripherals. It connects to the REva motherboard via SO-DIMM interface for rapid application development and evaluation.
For engineers reviewing the ST72325-D/RAIS datasheet, ST72325-D/RAIS pinout, ST72325-D/RAIS application, or ST72325-D/RAIS equivalent, this board enables hands-on validation of ST7-based firmware, peripheral configuration (e.g., ADC sampling, I²C sensor interfacing), and low-power mode behavior across industrial control and embedded instrumentation use cases.
Technical Context
The ST72325-D/RAIS integrates the ST72F325AR9 MCU - a member of STMicroelectronics' ST7 family - with 32 KB Flash, 1 KB RAM, 10-bit ADC (8 channels), three 16-bit timers, and serial interfaces including SPI, I²C, and UART. It operates at up to 8 MHz with supply voltage configurable for 3.3 V or 5 V via REva motherboard jumpers.
Designed for plug-and-play compatibility with the REva motherboard, the daughterboard uses a standard SO-DIMM connector and includes oscillator footprint and clock source selection jumper, enabling flexible clocking options (internal RC, external crystal, or ceramic resonator) without hardware modification.

FAQ
Does ST72325-D/RAIS include an onboard debugger?
No. ST72325-D/RAIS is a standalone daughterboard and does not contain an embedded debugger. Debugging and programming are performed via the REva motherboard's integrated RLink using SWIM (for STM8) or ICC (for ST7) protocols over USB.
What software tools are required to develop firmware for this board?
Ride7 IDE from Raisonance is required, including its ST7 C compiler (free version supports up to 2 KB code), SIMICE simulator, RBuilder peripheral configurator, and debugger. RFlasher7 may be used for standalone programming.
Can ST72325-D/RAIS operate independently without the REva motherboard?
No. It lacks power regulation, USB interface, and debugging circuitry. It must be mounted on the REva motherboard, which provides USB-powered operation, I/O expansion, analog/digital test points, and host PC connectivity via RLink.
Is the ST72F325AR9 MCU on this board factory-programmed with bootloader or demo firmware?
No. The ST72F325AR9 is delivered unprogrammed. Users must load firmware via Ride7 or RFlasher7 using the REva motherboard's RLink interface and ICC protocol.
