Product details
Overview
CY9AF131KAPMC-G-UNE2 from Cypress Semiconductor (now Infineon) is a 4 Mbit (512K × 8) low-power SRAM with PowerSnooze™ and embedded ECC, designed for high-reliability data buffering in industrial controllers and medical instrumentation. It delivers 10 ns access time at 2.2–3.6 V, supports 15 µA deep-sleep current, includes dedicated ERR output for single-bit error detection/correction, and operates across –40°C to +85°C.
For engineers reviewing the CY9AF131KAPMC-G-UNE2 datasheet, CY9AF131KAPMC-G-UNE2 pinout, CY9AF131KAPMC-G-UNE2 application, or CY9AF131KAPMC-G-UNE2 equivalent, key selection criteria include ECC-enabled data integrity, ultra-low IDS in deep-sleep mode, TTL-compatible I/O, multi-voltage support (1.65–2.2 V / 2.2–3.6 V / 4.5–5.5 V), and TSOP II package compatibility for space-constrained PCB layouts.
Technical Context
This SRAM integrates on-die ECC encoding/decoding logic that detects and corrects single-bit errors in real time without external circuitry, with ERR asserted as an open-drain output upon correction. Its PowerSnooze™ architecture enables seamless transition between active (ICC = 38 mA typ), standby (ISB2 = 6 mA typ), and deep-sleep (IDS = 15 µA) modes via dedicated DS pin control.
The device uses standard asynchronous SRAM protocol: CE and OE low for read, CE and WE low for write, with address latching on rising edge of CE. All I/O pins (I/O0–I/O7) are bidirectional and TTL-compatible, supporting 1.0 V data retention during power loss when VCC ≥ 1.65 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K words × 8 bits) - provides sufficient buffer depth for real-time sensor fusion or firmware stack storage in resource-constrained systems. |
| Access Time (tAA) | 10 ns at 2.2–3.6 V - enables direct interfacing with 100 MHz microcontrollers without wait states. |
| Deep-Sleep Current (IDS) | 15 µA max - extends battery life in portable diagnostic equipment during idle periods without data loss. |
| ECC Functionality | Detects and corrects single-bit errors per access - eliminates need for external error-handling firmware or redundant memory mapping. |
| Operating Voltage | 1.65–2.2 V / 2.2–3.6 V / 4.5–5.5 V - supports legacy 5 V logic, modern low-voltage MCUs, and mixed-supply systems. |
| Data Retention | 1.0 V minimum VCC - maintains stored configuration or calibration data during brown-out conditions. |
| Temperature Range | –40°C to +85°C industrial grade - validated for deployment in factory automation PLCs and outdoor IoT gateways. |
Pinout & Package
Package: 44-pin TSOP II (10.16 mm × 20.0 mm, 0.8 mm pitch), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CE | Chip Enable (active-low) | Primary device select; must be low for read/write cycles; high disables all internal operations including ECC logic. |
| /OE | Output Enable (active-low) | Controls I/O bus direction; low enables output drivers, high places I/O pins in high-impedance state. |
| /WE | Write Enable (active-low) | Asserted with /CE low to initiate write; timing-critical for setup/hold relative to address and data edges. |
| DS | Deep Sleep (active-low) | Puts device into 15 µA retention mode; overrides /CE, disabling all access while preserving data at ≥1.0 V VCC. |
| ERR | Error Flag Output (open-drain) | Pulled low when ECC detects/corrects a single-bit error; requires external pull-up for system-level fault logging. |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; TTL-compatible voltage thresholds enable direct connection to legacy MCU GPIOs. |
| A0–A18 | Address Inputs | 19-bit address bus selects one of 524,288 locations; A0 is LSB, A18 is MSB. |
Key Features
| Feature | Design Value |
|---|---|
| PowerSnooze™ Deep Sleep Mode | Reduces current to 15 µA while retaining full 4 Mbit content - critical for battery-powered edge nodes requiring >1-year shelf life. |
| On-Die ECC Logic | Hardware-accelerated single-bit error detection and correction per memory access - eliminates software overhead and improves MTBF in safety-critical systems. |
| Dedicated ERR Output | Open-drain flag signals corrected errors without CPU polling - enables deterministic fault response in real-time OS environments. |
| Multi-Voltage Operation | Three independent VCC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V) - simplifies integration across generations of host processors without level-shifting. |
| TTL-Compatible I/O | Meets standard 1.4 V VIH / 0.4 V VIL thresholds at 3.0 V VCC - ensures interoperability with legacy 3.3 V and 5 V microcontrollers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC-enabled SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV5128BLL-10MLI | No embedded ECC; requires external error-checking logic; 10 ns access, 3.3 V only; 44-pin TSOP II. | Lacks hardware ECC - increases firmware complexity and CPU load for error handling in safety-critical use cases. | Select only if cost sensitivity outweighs reliability requirements and external ECC implementation is acceptable. |
| AS6C4008-10TIN | Includes parity (not full ECC); 10 ns access; 3.3 V only; 32-pin SOJ; no ERR pin or deep-sleep mode. | Provides basic error detection only; cannot correct errors or signal correction events - insufficient for IEC 62304 Class C software. | Choose only for non-safety applications where parity suffices and board space constraints favor SOJ over TSOP II. |
Compared with IS61WV5128BLL-10MLI and AS6C4008-10TIN, CY9AF131KAPMC-G-UNE2 uniquely combines hardware ECC correction, ERR signaling, and 15 µA deep-sleep retention - delivering verified data integrity and ultra-low-power operation in a single monolithic solution.

FAQ
Does CY9AF131KAPMC-G-UNE2 support automatic error correction without CPU intervention?
Yes. The device performs single-bit error detection and correction autonomously within each memory access cycle using on-die ECC logic. When a correctable error occurs, it is fixed before data is placed on the I/O bus, and the ERR pin asserts low to notify the system - no firmware action is required for correction.
What is the minimum VCC required to retain data in deep-sleep mode?
The device guarantees data retention down to 1.0 V VCC in deep-sleep mode (DS = low). This specification is tested and guaranteed across the full industrial temperature range (–40°C to +85°C), enabling reliable operation during brown-out conditions without backup capacitors.
Can the ERR pin be used as a general-purpose interrupt output?
No. ERR is a dedicated open-drain output that pulses low only when a single-bit error is detected and corrected. It does not latch, cannot be cleared by software, and has no programmable threshold or duration - its sole purpose is to signal ECC correction events for system-level logging or diagnostics.
Is CY9AF131KAPMC-G-UNE2 compatible with legacy 5 V microcontrollers?
Yes. The device supports 4.5–5.5 V VCC operation with TTL-compatible input thresholds (VIH = 2.2 V min, VIL = 0.8 V max) and output drive strength sufficient to drive standard 5 V CMOS loads, enabling direct interface with legacy 8051, PIC, or FPGA-based controllers without level shifters.
