STMicroelectronics PSD813F2/PSD833F2/PSD834F2/PSD853F2/PSD854F2 Flash ISP Peripheral Datasheet
This document describes the PSD813F2, PSD833F2, PSD834F2, PSD853F2, and PSD854F2 Flash In-System Programmable (ISP) peripherals designed for 8-bit microcontrollers. The device features dual bank flash memories with up to 2 Mbit of primary memory and 256 Kbit of secondary memory, allowing concurrent read operations while erasing or writing the other bank.
Key capabilities include a PLD with over 3000 gates (CPLD and DPLD), 27 individually configurable I/O ports, and an enhanced JTAG serial port for in-system programming. The datasheet details architectural features such as battery-backed SRAM, power management units, reset timing, and specific register descriptions for memory blocks, instructions, and port configurations.
