Silicon Labs 8051-based MCU SoCs stake a claim on IoT

NUREMBERG, Germany — Falling costs for 32-bit microcontrollers (MCUs) has prompted considerable speculation about them displacing 8-bit MCUs for new designs. But 8-bit MCUs aren't nearly dead yet. Silicon Labs just announced at Embedded World a new series of 8-bit MCUs that target a range of cost-, power-, and space-sensitive applications in the Internet of Things (IoT).

Silicon Labs is investing in new 8-bit devices, the company's director of marketing for 8-bit MCUs Tom Pannell told EE Times, because developers are looking for simplicity to speed their design efforts. “We've been working to provide performance, value, and ease-of-use for IoT developers,” said Pannell. “The 8-bit architecture is easier to use than others, and offers lower cost and power. Our high-speed, pipelined 8051 core provides the performance.”

The company also sees the 8-bit market as still thriving. The company quoted a report from Tom Hackenberg of market research firm IHS indicating that 8-bit devices will retain a third of the MCU market for several more years. Indeed, IHS expects the market to growing in value, reaching $7.8 billion in 2018.

To address a diverse range of applications, Silicon Labs has released the new EFM8 MCU family as three product lines, all with an apiary theme: Busy Bee, Sleepy Bee, and Universal Bee. A set of six low-cost (<$30) starter kits for these devices were also announced.

  1. “”The 8-bit architecture is easier to use than others”… Err, not true. 8-bit gives all sorts of problems with limited address spaces etc, and 8051 architecture is the worst with archaic RAM handling etc.nnThe fastest 8051s are still slower than middl

  2. “If anything FUD is going the other direction. Limited address space, for example, isn't an issue since designs where an 8051 (or another 8-bit micro) would make sense by definition don't require huge address spaces. Thousands (possibly an understatement)
