Microchip Technology has introduced the PIC16F132 and PIC18-Q35 8-bit families of MCUs, as an upgrade over the PIC16F13145, which combine traditional embedded control with integrated Configurable Logic Blocks (CLB), to bring CPLD-like programmable logic directly onto the microcontroller die. The main difference between the two families is in logic density, where the PIC16F132x includes 32 Basic Logic Elements (BLEs), and the PIC18-Q35 offers 128 BLEs. Alongside the CLB, these MCUs also integrate security and voltage management features. Programming and Debugging Interface Disable (PDID) provides anti-tamper protection against unauthorized firmware access, and Multi-Voltage I/O (MVIO) allows direct communication across different voltage domains without external level shifters. The company also mentions that by executing logic functions on dedicated hardware rather than in software, the CLB architecture reduces CPU load and power consumption while ensuring deterministic behavior. This makes the devices well-suited for timing-critical applications such as motor control, industrial automation, consumer electronics, […]

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface
Nuvoton’s new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A, Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY.
