Freescale is promoting ZigBee as the wireless link for health and wellness products with a consumer physical activity monitor reference design.
The data acquisition system incorporates a pedometer, electrocardiograph, food intake table, and a stopwatch.
It is hardware-ready to support a ZigBee software stack, and includes a USB stack that supports the personal healthcare device class (PHDC).
Underneath is the firm's MCF51MM microcontroller which has a ColdFire V1 core and integrated analogue peripherals.
"Biometric data can be saved and stored in the integrated Micro SD card reader, and a touch-sensing interface allows the user to control the device through a capacitive film. All documentation, hardware and software design files are provided to facilitate prototyping," said the firm.
At the same time it announced something for the medical instrument market: an application development tool for pulse oximetry.
The hardware, called MED-SPO2, plugs into the firm's 'Tower' development hardware (pictured), and includes software stacks and hardware design files for 8 and 32bit processor versions.
"The board can connect to a pulse oximeter sensor and send the data to a microcontroller with an integrated measurement engine such as the Kinetis K50, MCF51MM or 9S08MM devices," said the firm. "Compatible MCUs perform the required signal conditioning using integrated transimpedance and operational amplifiers."
The sensor in not included in the kit, and the board is not yet available - Freescale isn't taking orders until Q4.
Towers TWR-K53N512, -MCF51MM and -S08MM128 support the processors and allow the addition of peripheral modules for graphic display, segmented LCDs, USB and Ethernet.
