PSD4135G2V Flash在系统可编程外设的16位MCU
The PSD4135G2 and PSD4135G2V programmable microcontroller (MCU) peripherals bring in-system-programmability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. The devices combine many of the peripheral functions found in MCU based applications (see Figure 1). They consist of six major types of functional blocks:
- Memory blocks
– 4 Mbit of Flash memory
– A secondary Flash memory for boot or data
– Over 3,000 gates of Flash programmable logic
– 64 Kbit SRAM - PLD blocks
- Bus interface
- Reconfigurable I/O ports
- Power management unit
- JTAG-ISP interface
The functions of each block are described in the following sections. Many of the blocks
perform multiple functions, and are user configurable.
The PSD4135G2 and PSD4135G2V devices offer two methods to program PSD Flash memory while the PSD is soldered to a circuit board
