AN59389 - Host Sourced Serial Programming for CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7/S | Cypress Semiconductor
AN59389 - Host Sourced Serial Programming for CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7/S
Host Sourced Serial Programming (HSSP) is a method of in-circuit serial programming (using ISSP protocol) of the CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7 devices from an onboard host processor. AN59389 explains how to use and port the HSSP code example, provided along with this application note, to the desired host processor for programming the CY8C20xx6A, CY8C20xx6AS, CY8C20xx6L and CY8C20xx7 devices.
Cypress’s PSoC microcontrollers are easy-to-use, flexible, and have a cost-effective mix of reprogrammable analog and digital resources. These features provide many opportunities for creative designs, one of which is programming the PSoC serially by an on-board host processor. This method is used to install or update firmware in-field or even completely reprogram the PSoC for a different function.
