The PSD4235G2-90UI from STMicroelectronics is a versatile Flash in-system programmable (ISP) integrated circuit designed for 16-bit microcontrollers. It offers dual-bank Flash memories with 4Mbit of primary Flash and 256Kbit of secondary Flash, enabling concurrent read operations from one bank while erasing or writing to the other. This device also includes 64Kbit of SRAM and PLD capabilities with over 3000 gates.
Key electrical specifications include a single supply voltage of 5V ± 10% and memory access times of 70ns for both Flash and SRAM. The IC supports in-system programming via JTAG and features high endurance for Flash memory (100,000 erase/write cycles) and data retention of 15 years.
Packaged in an 80-lead LQFP, the PSD4235G2-90UI is suitable for surface mount applications. It provides 7 I/O ports with 52 individually configurable I/O pins, which can be used for MCU I/Os, PLD I/Os, latched MCU address output, or special function I/Os. The device also includes an internal page register for expanding the microcontroller address space.
