Product details
Overview
CY7C1051H30-10BVXI from Infineon Technologies (formerly Cypress) is an 8-Mbit (512K × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), TTL-compatible I/O, 10 ns access time, and operation across 2.2–3.6 V. It serves as a high-reliability data buffer in industrial control modules requiring ECC protection against soft errors.
For engineers reviewing the CY7C1051H30-10BVXI datasheet, CY7C1051H30-10BVXI pinout, CY7C1051H30-10BVXI application, or CY7C1051H30-10BVXI equivalent, key selection criteria include ECC implementation without automatic write-back, TSOP II package compatibility, 10 ns tAA timing, and dual-byte enable (BHE/ BLE) for partial-word writes in real-time deterministic systems.
Technical Context
The device integrates dedicated ECC encoder/decoder logic adjacent to the memory array, performing on-the-fly single-bit correction during read cycles without CPU intervention. Its address decoding supports full 19-bit addressing (A0–A18) for 512K word access, with separate byte enables enabling independent upper/lower 8-bit writes.
It operates in three power states: active (ICC = 90 mA typ at 100 MHz), standby with CE high (ISB2 = 20 mA typ), and data retention at 1.0 V (ICCDR ≤ 30 mA). Input/output buffers meet TTL voltage thresholds across the full 2.2–3.6 V VCC range, ensuring interoperability with legacy 3.3 V and mixed-voltage controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 8 Mbit (512K words × 16 bits); supports full-word or byte-aligned access without external glue logic |
| Access time (tAA) | 10 ns max; enables direct interface with 100 MHz bus clocks without wait states |
| ECC capability | Single-bit error correction per 16-bit word; detects but does not auto-write-back corrected data |
| VCC range | 2.2 V to 3.6 V; compatible with both 2.5 V and 3.3 V system rails |
| Standby current (ISB2) | 20 mA typical at VCC ≥ 3.4 V; supports low-power hold mode in battery-backed systems |
| Data retention voltage | 1.0 V minimum; allows extended retention during brown-out or controlled power-down sequences |
Pinout & Package
Package: 44-pin TSOP II (Thin Small Outline Package, Type II), RoHS-compliant, body size 10.16 mm × 20.0 mm × 1.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address inputs | 19-bit address bus supporting full 512K-word addressing; no external address multiplexing required |
| I/O0–I/O7 | Data bus (lower byte) | Driven or tri-stated based on BLE assertion; enables 8-bit sub-word writes without masking logic |
| I/O8–I/O15 | Data bus (upper byte) | Driven or tri-stated based on BHE assertion; supports independent upper-byte updates |
| /CE | Chip enable (active low) | Primary device select; places all I/Os in high-Z when deasserted, enabling multi-SRAM bus sharing |
| /OE | Output enable (active low) | Controls read data output only; allows address setup before data valid window |
| /WE | Write enable (active low) | Initiates write cycle; latches address and data on falling edge with CE and OE inactive |
| /BLE | Byte low enable (active low) | Enables write/read of I/O0–I/O7 only; used for 8-bit peripheral interfacing |
| /BHE | Byte high enable (active low) | Enables write/read of I/O8–I/O15 only; supports split-bus architectures |
Key Features
| Feature | Design Value |
|---|---|
| Embedded ECC logic | On-die correction circuitry eliminates need for external ECC controller or software overhead |
| Dual byte enable (/BHE & /BLE) | Hardware-selectable 8-bit access avoids software bit-masking and reduces bus turnaround latency |
| TTL-compatible I/O | Direct interface with legacy 3.3 V microcontrollers and FPGAs without level-shifting |
| Low ISB2 standby current | 20 mA typical at full VCC enables use in always-on industrial nodes with thermal constraints |
| 1.0 V data retention | Preserves memory contents during undervoltage events down to 1.0 V, supporting graceful shutdown |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS7C35128P-10TIN | No integrated ECC; requires external error detection logic | Suitable for cost-sensitive designs where ECC is implemented in FPGA or processor | Select if system-level ECC is already present and board space is constrained |
| IS61WV51216BLL-10MLI | 10 ns access, no ECC, lower ISB2 (15 µA vs. 20 mA) | Better suited for ultra-low-power sleep modes, but lacks bit-error resilience | Choose when power budget dominates over reliability in non-safety-critical logging |
Compared with AS7C35128P-10TIN and IS61WV51216BLL-10MLI, CY7C1051H30-10BVXI uniquely delivers on-die ECC correction at 10 ns speed-critical for deterministic systems where software ECC introduces unacceptable latency or complexity.

FAQ
Does CY7C1051H30-10BVXI support automatic error correction write-back?
No. The device performs single-bit error correction during read operations and outputs corrected data, but it does not automatically write the corrected value back to the memory array. Error correction is read-only; any write-back must be handled by external logic or firmware.
What is the maximum operating temperature range for this part?
The CY7C1051H30-10BVXI is rated for the Industrial grade temperature range of –40 °C to +85 °C. This is confirmed in the "Operating Range" table on page 5 of the datasheet (Rev. *D), and applies to all electrical specifications including tAA, ICC, and ISB2.
Can this SRAM be used with a 2.5 V microcontroller interface?
Yes. Its VCC range is 2.2 V to 3.6 V, and its TTL-compatible inputs accept VIH ≥ 2.0 V and VIL ≤ 0.6 V at 2.5 V operation-fully meeting standard 2.5 V logic thresholds. Output drive strength remains compliant per DC specs at 2.5 V VCC.
Is the 44-pin TSOP II package lead-free and RoHS-compliant?
Yes. The "Features" section on page 1 explicitly states "Available in Pb-free 44-pin TSOP II", and the ordering code suffix 'VXI' denotes a lead-free, RoHS-compliant TSOP II package per Infineon's packaging nomenclature.
