Infineon Technologies CY7C1061GN30-10BVJXIT

Overview

CY7C1061GN30-10BVJXIT from Cypress Semiconductor is a 16-Mbit (1,048,576 × 16) asynchronous CMOS static RAM with 10 ns access time, 2.2–3.6 V operation, dual chip enable (CE1/CE2), and byte-wide write control via BHE/BLE. It delivers 90 mA active current at 100 MHz and supports data retention down to 1.0 V in low-power hold mode. Used in industrial embedded controllers requiring fast, non-volatile-critical SRAM buffering.

For engineers reviewing the CY7C1061GN30-10BVJXIT datasheet, CY7C1061GN30-10BVJXIT pinout, CY7C1061GN30-10BVJXIT application, or CY7C1061GN30-10BVJXIT equivalent, key selection criteria include tAA = 10 ns timing, dual CE architecture for hierarchical memory decoding, VFBGA-48 (BVJX) package compatibility, and 1.0 V data retention capability under power loss scenarios.

Technical Context

This SRAM implements a fully asynchronous interface with independent high- and low-byte write enables (BHE, BLE) and dual chip enables (CE1, CE2) that form a logical AND gate for device selection. Address decoding covers A0–A19 (20-bit), supporting full 1M-word addressing without external address latching.

It operates across two voltage domains: 2.2–3.6 V for active read/write and 1.0 V minimum for data retention. Power-down is automatic upon CE deassertion, with ISB2 = 20 mA (typ) standby current under CMOS input conditions, enabling low-quiescent designs in battery-backed systems.

FAQ

What is the maximum clock frequency supported for continuous read/write bursts?

This is an asynchronous SRAM with no internal clock. Its 10 ns access time (tAA) and 10 ns output hold time (tOH) allow interfacing with microcontrollers or FPGAs operating bus frequencies up to 100 MHz, provided address/data setup/hold times are met. No external clock signal is required or accepted.

Does CY7C1061GN30-10BVJXIT support true dual-port operation?

No. It is a single-port asynchronous SRAM with one shared address/data bus. While BHE and BLE enable independent byte writes, it does not support simultaneous read and write operations on separate ports. For true dual-port functionality, Cypress's CY7C1356 or similar devices must be selected.

Can CE1 and CE2 be tied together for single-enable operation?

Yes, but only with external inversion: CE2 must be held HIGH (e.g., pulled to VCC) while CE1 serves as the sole chip enable. Direct tying of CE1 and CE2 violates the required logic condition (CE1 = LOW & CE2 = HIGH), causing permanent deselection. A simple inverter on CE2 enables standard single-CE usage.

Is the 48-ball VFBGA (BVJX) package RoHS and REACH compliant?

Yes. Per Cypress's ordering code suffix "XIT", this variant is lead-free (Pb-free), RoHS-compliant, and meets REACH SVHC requirements. The "T" denotes tape-and-reel packaging, and "I" indicates industrial temperature grade (–40 °C to +85 °C), both confirmed in the official datasheet revision *C.
