MCUs are made for in-circuit program upgrades

New range of I/O type microcontroller devices boast a -40 to +85C operating temperature range and excellent noise immunity.

With an internal Flash program memory that can be reprogrammed up to 100,000 times and an internal EEPROM which can undertake up to a million read and write operations, a new range of I/O type microcontroller devices from Solid State Supplies also boast a -40 to +85C operating temperature range and excellent noise immunity.

Consisting of five devices, the range is based on a Holtek 8bit RISC core, Flash memory capacity of 1-8Kbit, EEPROM capacity of 128 or 256byte and 64-224byte of RAM that provides a wide choice of flexible memory options.

The reprogramming facilities, along with an integrated in-system programming feature, provide the designer with a simple and expedient means for in-circuit program upgrades.

The EEPROM data memory in each device can be used to store parameters such as calibration or other data, either during the production process or during normal device operation.

As this type of memory is nonvolatile in nature, it has the advantage of saving data even after power is removed.

The devices are supplied in a range of package types, including DIP, SKDIP, SOP, SSOP and QFP types with 18 to 64 pins, making them ideal for applications in electrical appliances, security products, industrial control, consumer electronics and automotive peripheral products.

Fully supported by Windows based HT-IDE300 functional hardware and software development tools and features such as real time emulation, breakpoint functions and trace analysis, the component also has an integrated device programmer onboard, giving designers all the necessary tools and support to ensure that their applications are efficiently developed and debugged.
