CAMBRIDGE, UK — The H8/38606F announced by Renesas Technology Europe is a very low power microcontroller designed with 48-kbytes of on-chip flash memory for smart sensor applications.
Delivered in a 5x6-mm 32-pin QFN package the H8/38606F offers a fast oscillator start up feature, where the main oscillator can start up in around 20 microseconds using an external resonator.
This makes it well suited for any application which spends most of its time asleep in the lowest power modes, and then wakes to take readings or to communicate.
The asynchronous timer on the H8/38606F also makes the device suitable for many battery powered applications which count pulses and keep time, being able to count external pulses and use its internal real time clock to achieve an average power consumption of around 0.5microA.
The on-chip high-resolution 10-bit A/D converter with a wide sampling range will find good use in applications such as water and flow meters.
The H8/38606F Tiny SLP supports many methods of low power communications, including a USART with built-in IrDA interface that can be driven at up to 2400 baud from a 32 kHz oscillator.
A specially-designed 16-bit timer along with the two on-board analogue comparators also provide solutions for a variety of commonly used power and data over two wire communications schemes.
This timer module can also be used for a number of other purposes, including driving a variety of motors, and is capable of generating up to 4 channels of PWM output.
An on-chip watchdog timer with built-in oscillator, along with power on reset and the on-chip oscillator also makes the H/38606F easy to design with in systems where reliability is an issue.
The chip is supported by Renesas' Embedded Workbench and the E8a low cost on-chip debugger, providing all the tools required to evaluate and develop applications with the device.
