ROM-based USB MCUs save on volumes
ROM versions of standard 8051-based USB microcontrollers are especially suited for high-volume applications where cost matters more than flexibility.
Atmel Corp has added three ROM devices to its family of standard 8051-based USB microcontrollers Complementing the available Flash versions, the new devices are especially suited for high-volume applications where cost matters more than flexibility and where the code is stable

Smart MCU aims for point-of-sale control
The AT91SAM9261 smart ARM microcontroller (SAM) is based on the ARM926EJ-S processor and is billed as the industry's first ultra-low-power deterministic microcontroller.
Controller maintains automotive system safety
With its built-in driver functions and complete monitoring system, the ATA6814 is a unique solution beneficial for all safety-relevant automotive electronics.
Based on Atmel's 8051 X2 core which executes an instruction in 6 clock periods, the new AT83C5134, AT83C5135 and AT83C5136 have 8, 16 and 32Kbyte of ROM code memory, respectively.
In addition, two variants of the 32Kbyte version are available: AT83EC5136 and AT83EI5136 which include 512byte and 32Kbyte, respectively, of EEPROM for data storage.
The products feature a USB Full-Speed controller, UART, SPI and a two wire interface allowing an easy connection to companion devices.
The existing AT89C5130 and AT89C5131 devices, with 16 and 32Kbyte Flash, can be used for development, flexibility and pre-production as pin-to-pin and binary compatibility are preserved when migrating to the new ROM devices.
These devices are available with 3.3V supply voltage and support six programmable USB endpoints.
Offered in a 32-pin 5 x 5mm and a 48-pin 7 x 7mm QFN packages, the new ROM devices provide a broad range of memory sizes for the lowest cost and the smallest physical dimensions.
"We wanted to add USB connectivity to our new range of modular drive controllers so our customers can easily configure", said Michael Jensen, Purchasing Manager Electronics at Danfoss Drives.
"Our products must provide long lasting quality in harsh industrial environments and Atmel's 8051 USB microcontrollers solutions meet all our needs at the right cost".
The AT83C5134, AT83C5135 and AT83C5136 are available now in 32-pin QFN packages.
Pricing starts at US $1.30, US $1.40 and US $1.55 for 10,000-unit volumes.
The AT83C5136 is also available in a 28-pin SOIC package, 48-pin QFN package and a 64-pin VQFP package.
