PSD9XX Family PSD935G2 Configurable Memory System on a Chip for 8-Bit Microcontrollers 1.0 Introduction The PSD9XX series of Programmable Microcontroller (MCU) Peripherals brings In-System-Programmability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. PSD9XX devices combine many of the peripheral functions found in MCU based applications: 4 Mbit of Flash memory A secondary Flash memory for boot or data Over 3,000 gates of Flash programmable logic 64 Kbit SRAM Reconfigurable I/O ports Programmable power management. 1 PSD9XX Family 1.0 Introduction (Cont.) 2 PSD935G2 The PSD935G2 device offers two methods to program PSD Flash memory while the PSD is soldered to a circuit board. t In-System Programming (ISP) via JTAG An IEEE ...
