Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
The 11XX010, 11XX020, 11XX040, 11XX080 and 11XX160 are the first single-I/O EEPROM devices that can support datarates from 10 to 100kHz; and the only 1, 2, 4, 8 and 16Kbit EEPROMs available in 3-pin SOT-23 packages (in addition to other higher-pin-count packages).
The new devices also include advanced such as status registers; software write protection for quarter, half or full array; noise filtering, and robust ESD protection for the highest reliability.
The UNI/O bus and EEPROM devices were developed in response to market trends toward smaller consumer-electronic products with more features and functionality.
With this new bus, only one I/O pin is needed for communication between the EEPROM device and the microcontroller.
Evaluation is simplified because the UNI/O memory devices are available in 8-pin packages with pinouts that overlay any standard I2C or SPI EEPROM socket.
This means that existing hardware can be used with the available UNI/O software drivers for a quick test.
The UNI/O memory devices are supported by the new MPLAB Starter Kit for Serial Memory Products, the MPLAB PM3 Universal Device Programmer and by software drivers available for Microchip's PIC MCUs from the company's website.
Drivers for other MCUs will be available in the future.
The new devices are offered in two versions: the 11LCXX0 versions operate from 2.5 to 5.5V, and the 11AAXX0 versions operate from 1.8 to 5.5V.
All the new memory devices are available in 3-pin SOT-23 as well as 8-pin PDIP, MSOP, SOIC and 2 x 3mm TDFN packages.
Samples of the 16Kbit 11XX160 EEPROM devices are available now.
Samples and production quantities of the smaller devices are expected in June.
