Product details
Overview
PSD813F2VA-15M from STMicroelectronics is a Flash in-system programmable (ISP) peripheral IC for 8-bit microcontrollers, integrating dual-bank Flash (1 Mbit primary + 128 Kbit secondary), 128 Kbit SRAM, 27 reconfigurable I/O ports, and a 3000-gate PLD with CPLD/DPLD architecture. It supports concurrent read/erase/write operations and operates at 5 V with 15 MHz maximum clock frequency. Used in legacy industrial control systems requiring field-upgradable firmware and flexible address decoding.
For engineers reviewing the PSD813F2VA-15M datasheet, PSD813F2VA-15M pinout, PSD813F2VA-15M application, or PSD813F2VA-15M equivalent, key selection criteria include ISP JTAG support, dual-bank Flash concurrency, PLD-based chip select decoding, and compatibility with 80C51/68HC11 bus interfaces.
Technical Context
The device implements a tightly coupled memory subsystem with two independent Flash banks enabling simultaneous execution and reprogramming - critical for zero-downtime firmware updates. Its PLD block includes 16 output macrocells (OMCs) and 24 input macrocells (IMCs), configurable as combinatorial or registered logic for custom address decoding and glue logic replacement.
It features an internal page register that expands MCU address space by 256×, and supports multiplexed/non-multiplexed 8-bit buses via dedicated control signals (ALE, RD, WR, CS). Power management includes automatic power-down (APD) triggered by idle bus cycles, reducing active current to 25 mA typical in Turbo mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Primary Flash Memory | 1 Mbit (8 × 128 Kbit uniform sectors); enables firmware partitioning and secure boot loader storage. |
| Secondary Flash Memory | 128 Kbit (4 × 32 Kbit uniform sectors); used for configuration data, calibration tables, or parameter storage. |
| SRAM Capacity | 128 Kbit (16 K × 8); provides fast scratchpad memory for real-time MCU data buffering. |
| PLD Logic Gates | 3000 gates; replaces discrete logic chips for address decoding, interrupt arbitration, and peripheral enable control. |
| Max Clock Frequency | 15 MHz; defines maximum bus transaction rate and PLD timing closure for 5 V operation. |
| I/O Ports | 27 reconfigurable pins; supports MCU I/O, PLD I/O, latched address output, and open-drain modes (16 pins). |
| JTAG Interface | IEEE 1149.1-compliant serial port; enables full-chip in-system programming without socket removal. |
Pinout & Package
PSD813F2VA-15M is housed in a 52-pin PQFP (Plastic Quad Flat Package) with 0.65 mm pitch, ECOPACK®-compliant and RoHS-conformant. Pin assignments follow STMicroelectronics' standard layout for PLCC52/PQFP52 compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | 5 V ±10% main supply for core logic and I/O drivers. |
| GND | Ground reference | Common return path for all digital and PLD circuits. |
| A0–A15 | Address inputs | 16-bit address bus interface; supports up to 64 KB direct addressing without page register. |
| D0–D7 | Data bus | 8-bit bidirectional data path compatible with 80C51, 68HC11, and 80C251 MCUs. |
| RD, WR, ALE | Control signals | Standard 80C51-style bus strobes; enable memory read/write and address latch enable timing. |
| TCK, TMS, TDI, TDO | JTAG test interface | Serial programming and debug access; allows factory programming and field firmware updates. |
| CSI (PD2) | Chip select input | Active-low enable signal; gates all internal memory and PLD accesses when asserted. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-bank Flash concurrency | Read from one bank while erasing/writing the other - eliminates system halt during firmware update. |
| Configurable PLD architecture | CPLD (16 OMCs + 24 IMCs) + DPLD for user-defined chip select decoding - replaces 74-series logic and reduces BOM count. |
| Page register expansion | 256× address space extension - enables >64 KB code/data mapping on 8-bit MCUs with limited address pins. |
| 16 open-drain I/Os | Supports wired-AND interrupt sharing, I²C-like signaling, and level translation with external pull-ups. |
| Automatic Power-down (APD) | Reduces standby current to 20 µA typical; triggered by bus inactivity - extends battery life in portable industrial tools. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash+PLD peripheral applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PSD833F2VA-15M | 2 Mbit primary Flash + 256 Kbit secondary Flash; same PLD and I/O structure. | Higher firmware capacity for complex control algorithms; requires identical PCB footprint. | Select when firmware size exceeds 1 Mbit and board layout permits no change. |
| PSD813F4VA-15M | Same Flash/SRAM/PLD specs but with 4 uniform sectors in secondary Flash (vs. 4 × 32 Kbit in PSD813F2VA-15M). | Sector erase granularity differs - impacts field update time and wear leveling strategy. | Choose only if legacy design specifically relies on 4-sector erase behavior documented in original PSD813F2VA-15M firmware. |
Compared with PSD833F2VA-15M, this part offers lower Flash density at identical speed and PLD capability - ideal for cost-sensitive designs where firmware fits within 1 Mbit. Versus PSD813F4VA-15M, it provides identical sector organization, ensuring drop-in compatibility for existing erase routines and protection bitmaps.

FAQ
Is PSD813F2VA-15M still in production?
No - STMicroelectronics has marked PSD813F2VA-15M as obsolete per Doc ID 7833 Rev 7. However, Aetrix Electronics maintains a verified inventory of authentic, traceable units with full lot documentation and extended lifecycle support for legacy system maintenance.
What MCU families does it interface with natively?
It supports 80C51, 80C251, 80C51XA, and 68HC11 MCUs via dedicated bus interface modes. Pin-compatible timing and control signal mapping are defined in Sections 15.5–15.8 of the datasheet, including ALE, RD, WR, and CS handling for multiplexed and non-multiplexed buses.
Can the PLD be reprogrammed independently of Flash memory?
Yes - the PLD configuration is stored in dedicated nonvolatile registers and can be updated separately using JTAG commands without affecting Flash contents. The DPLD and CPLD blocks retain their logic definitions across power cycles and Flash erase operations.
Does it support 3.3 V operation?
No - PSD813F2VA-15M is a 5 V-only device (VCC = 4.5–5.5 V). It lacks 3.3 V I/O tolerance and does not meet DC characteristics for 3 V operation; use only with 5 V MCUs or level-shifted interfaces.
