8 bit MCUs getting reinvented with improved performance

Well the embedded designers are now least inclined to use 8 bit MCUs in their design. However 8-bit still has some power to go. The IP from cast has interesting performance in power consumption and silicon area.

The new S8051XC3 8051 MCU Core from Cast is suggested for managing analog sensors or radios in Internet of Things and wearable electronics devices; or running deeply embedded systems.

S8051XC3 offers a Dhrystone 2.1 performance rating of 0.252 DMIPS/MHz, a 26.85 times speed up over the original 80C51 chip operating at the same frequency.
This extremely smart 8051 IP takes 6200 gates (65nm LP) and operate at a maximum CPU frequency exceeding 500 MHz.

With a dynamic power consumption 2.4µW/MHz, this 8051 IP matches the performance of 32-bit processors in power consumption.

Silesia Devices Sp. z o.o. is a microcontroller and processor IP development firm founded in 2013. Cast is the investor in Silesia.
