Description

The Flash memory HMS99C56S increases EPROM and ROM functionality with in-circuit electrical erasure and programming. It contains 4K, 8K, 16K, 24K or 32K bytes of program memory. This memory is both parallel and serial In-System Programmable(ISP). The ISP allows devices to alter their own program memory in the actual end product under software control through UART ports. A default serial loader(bootloader) program supports ISP of the Flash memory HMS99C56S. The programming does not require external 12V programming voltage. The necessary high programming voltage is generated on-chip using the standard VCC pins of the microcontroller.
