Product details
Overview
CY7C1061GE30-10BVJXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, 10 ns access time, and ERR output pin for real-time error indication. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V) and targets high-reliability industrial memory subsystems requiring data integrity in avionics control units.
For engineers reviewing the CY7C1061GE30-10BVJXIT datasheet, CY7C1061GE30-10BVJXIT pinout, CY7C1061GE30-10BVJXIT application, or CY7C1061GE30-10BVJXIT equivalent, this device delivers deterministic ECC correction without write-back, supports dual chip enable (CE1/CE2) addressing, and provides byte-level write control via BHE/BLE - critical for fault-tolerant embedded firmware storage and real-time diagnostics buffers.
Technical Context
This SRAM implements a synchronous, addressable memory array with dedicated ECC logic that detects and corrects single-bit errors on every read cycle. The ERR pin asserts high only when correction occurs, enabling external logging or system-level fault response without interrupt overhead.
It supports both single CE (CE) and dual CE (CE1/CE2) configurations, with CE2 used to gate CE1 activation - allowing hierarchical memory mapping in multi-bank systems. Byte enables (BHE/BLE) operate independently of OE and WE, permitting partial writes without bus contention or additional latching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 words × 16 bits); supports full-word or byte-aligned access without alignment penalty |
| Access Time (tAA) | 10 ns at VCC = 2.2–3.6 V; enables direct interface with 100 MHz microcontrollers without wait states |
| ECC Function | Single-bit error detection and correction per 16-bit word; no automatic write-back - preserves deterministic timing |
| Supply Voltage Ranges | 1.65–2.2 V, 2.2–3.6 V, and 4.5–5.5 V; allows drop-in replacement across legacy 5 V, modern 3.3 V, and ultra-low-power 1.8 V systems |
| Standby Current (ISB2) | 20 mA typical at VCC = 3 V; enables low-power retention mode during processor sleep without external power gating |
| ERR Output | Dedicated open-drain output asserted high on corrected read; eliminates need for software polling or status register reads |
| Data Retention | 1.0 V minimum VCC; maintains stored data down to battery-backed 1 V supply - critical for brown-out resilience |
Pinout & Package
Package: 48-ball Very Thin Fine-Pitch Ball Grid Array (VFBGA), 6 mm × 8 mm × 1.0 mm, RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1M-word decoding; A19 placed at ball G2 per BVJXI configuration |
| I/O0–I/O15 | Bidirectional Data Bus | 16-bit parallel interface; high-impedance when CE/OE/BLE/BHE inactive - enables shared bus topology |
| CE1, CE2 | Dual Chip Enable Inputs | Logical AND activation: CE = CE1 LOW AND CE2 HIGH; enables bank-select granularity in multi-SRAM systems |
| WE | Write Enable Input | Active-low control for write cycles; sampled synchronously with address setup - ensures reliable write strobing |
| OE | Output Enable Input | Active-low control for read data output; independent of WE - allows read-modify-write sequences |
| BLE, BHE | Byte Low/High Enable Inputs | Enable writes to lower (I/O0–I/O7) or upper (I/O8–I/O15) byte; support mixed-endian or packed data structures |
| ERR | Error Indication Output | Open-drain output asserted HIGH only when ECC corrects a single-bit error; requires external pull-up for logic-level compatibility |
| VCC, VSS | Power Supply Pins | Separate VCC balls (balls E1, F1) and VSS balls (balls D1, H1) minimize switching noise coupling into memory core |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ECC SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C31026B-10TIN | No integrated ECC; requires external Hamming logic or MCU-based correction - adds 3–5 ns latency and 20+ µA active current | Suitable only where error rates are negligible (e.g., lab-grade test equipment), not safety-critical systems | Select only if cost sensitivity outweighs reliability requirements and board space permits external ECC circuitry |
| IS61WV102416BLL-10MLI | 10 ns access but no ERR pin; ECC status must be polled via status register - increases software complexity and worst-case read latency | Acceptable in non-real-time industrial HMIs where occasional 100 µs latency spikes are tolerable | Choose when deterministic ERR signaling is unnecessary and register-based status checking aligns with existing firmware architecture |
Compared with AS7C31026B-10TIN and IS61WV102416BLL-10MLI, CY7C1061GE30-10BVJXIT uniquely delivers hardware-triggered ERR assertion and zero-overhead correction - essential for ISO 26262 ASIL-D and IEC 61508 SIL-3 certified memory subsystems where software-managed ECC introduces unacceptable timing uncertainty.

FAQ
Does CY7C1061GE30-10BVJXIT support automatic error write-back after correction?
No. The device performs single-bit error correction transparently during read cycles but does not automatically rewrite the corrected data back to the memory array. This design avoids write latency penalties and ensures deterministic 10 ns access timing under all conditions, as confirmed in datasheet Note 1 and Truth Table behavior on page 16.
What is the function of the ERR pin, and how should it be interfaced?
The ERR pin is an open-drain output that asserts HIGH only when a single-bit error is detected and corrected during a read operation. It must be externally pulled up to VCC with a 4.7 kΩ resistor. No internal pull-up exists, and leaving it floating may cause false triggers due to noise coupling, as specified in datasheet Note 6 and Figure 5.
Can CY7C1061GE30-10BVJXIT operate across multiple VCC ranges simultaneously?
No. The device must be powered from a single VCC supply within one of the three supported ranges: 1.65–2.2 V, 2.2–3.6 V, or 4.5–5.5 V. Mixing voltages violates Absolute Maximum Ratings (page 7) and risks latch-up or permanent damage. Each range has distinct VOH/VOL thresholds calibrated for its VCC min/max.
How does the dual chip enable (CE1/CE2) logic differ from single CE operation?
In dual CE mode, the device activates only when CE1 is LOW and CE2 is HIGH - forming a logical AND condition. This differs from single CE (pin CE only), where activation occurs on CE LOW alone. Dual CE enables hierarchical memory mapping, such as using CE2 as a bank select and CE1 as a chip select, as defined in the Functional Description section on page 1.
