Today we announced an expansion to our EFM8 Busy Bee 8-Bit MCUs, our cost-effective and high-performance MCUs for embedded applications. When performance in demanding environments matters, the new EFM8BB3 devices deliver. And they do it in a package as small as 3x3 mm2without compromising performance.
The BB3 family includes new industrial grade (I-grade) devices as well as more memory (64 kB) and additional peripherals including four DACs, four configurable logic units, higher speed ADC, and higher pin count options. An extended temperature range of -40 to +125 °C (ambient) expands the utility of these devices into industrial applications including motor control, lighting, and others.
The BB3 MCUs includes configurable logic module that can be used for a variety of digital functions, such as replacing system glue logic, aiding in the generation of special waveforms, or synchronizing system event triggers. Since the function of the logic is completely programmable, it reduces the challenge of interfacing other chips in the system. It also reduces the cost and board space required for glue logics. This reduces the PCB space and also allows for faster time-to-market.
For applications operating at a wide temperature range, maintaining high performance throughout is important. This eliminates the need for external thermistors to measure temperature and adjust analog trimming coefficient accordingly. There’s also no need for costly and time consuming calibration and trimming based on operating temperature.
As modern designs require smaller packages and wider temperature ranges, the EFM8BB I-grade MCUs offers 2-64 kbyte flash, 0.5-4 kbyte RAM, along with high-resolution 12-bit ADC, high-speed 12-bit DACs, low power comparators, voltage reference, enhanced throughput communication peripherals, and internal oscillators in packages as small as 3x3 mm2. This saves both cost and board space for applications that needs to operate at wide temperature range.
