Silicon Storage Technology Inc. (SST) added the SST89C58RC to its FlashFlex family of 8 b microcontrollers (MCUs).
The device is aimed at a variety of applications including high-definition multimedia interface (HDMI), HDTVs, audio-video (A/V) receivers, home appliances, industrial instruments, notebook PCs, DVD players, Blu-ray players, radio frequency (RF) modules and security applications such as fingerprint identification.
The new device is an 8051-based MCU featuring two system management buses (SMBus), each supporting up to 400 Kbps data throughput, in a 6 millimeter by 6 millimeter quad flat no lead (QFN) package.
The SST89C58RC supports operating voltages from 2.7 volts (V) to 5.5 V for implementation in applications with a variety of power supply requirements. It comes with 1 KB of on-chip random access memory (RAM) and up to 34 KB of embedded SuperFlash memory.
"The MCU market is very competitive, and to be successful semiconductor vendors must offer customers devices with the right blend of features, performance and ease of implementation," said Paul Lui, senior vice president, SST memory and special products business unit.
Lui said the device addresses two trends in mobile devices: minimizing board space and increasing functionality.
"We feel the SST89C58RC is a unique offering in the 8 b 8051 MCU market that will enable customers to design new products quickly and efficiently," he said.
The SST89C58RC is part of the FlashFlex family of 8 b MCU products with SST patented and proprietary SuperFlash nonvolatile flash memory cells.
SuperFlash memory uses a split-gate cell design and a thick-oxide tunneling injector.
All devices in the FlashFlex family use the 8051 instruction set and are pin-for-pin compatible with standard 8051 MCU devices.
In addition, all devices in the FlashFlex family feature in-system programming (ISP) and in-application programming (IAP), which enable the user to update the flash device in the field or in an application.
The SST89C58RC is now in production.
