Colorado Springs, Co. -- EM Microelectronic's newest 4-bit flash microcontroller in an 8-pin package called the EM6580, combines such features as true low current operation with no external components, A/D converter or 12-level voltage level detector and on-chip flash memory to create a multi-functional MCU.
The device's low voltage of from 2.0V to 5.5V, and low power consumption make it especially suitable for controlling tasks in battery-powered devices, household appliances and body-care products, according to Mougahed Darwish, president of the management board of EM Microelectronic. The MCU is housed in small SO-8 packages. The EM6580 is the flash counterpart of ROM-based EM6680. The two products are pin-to-pin and completely function compatible.
"This is a unique, small general purpose microcontroller consuming as low as 3.3uA in standby mode and requiring no external components. We first developed the ROM counterpart and many customers told us that they wanted a flash version to bring their products to market faster and to increase flexibility by allowing software change in the application, while preserving ultra low current consumption. This is what EM6580 is all about: it is an ideal choice for cost-sensitive applications requiring very low power consumption. Not only it is compact but it offers high performance for a product of its kind," said Darwish.
Features include true low current: 5.8uA active mode/3.3uA standby mode/0.32uA sleep mode, flash 4k x 16 bit, RAM 80 x 4 bit; 5 or 6 I/Os with 2 high drive outputs of 20mA, power-on-reset with power-check and brownout control, sleep counter reset: automatic wake-up from sleep mode (with 4 selectable timings), internal RC oscillator 32 kHz to 800 kHz and 8-bit serial interface. It is possible to store a unique serial ID number on each device produced, allowing for unique identification and traceability.
The units are available in SO-8, SO-14 packages and die form. Pricing for the EM6580 starts at 95 cents each in SO-8 in quantities of 10,000 pieces.
The EM6580 is supported by Windows-based simulator and emulator tools provided by EM Microelectronic, and is programmable with third party programmers. A demoboard is also available for initial evaluation and development.
