Infineon Technologies CY7C1061GE18-15BVJXIT

Overview

CY7C1061GE18-15BVJXIT 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, 15 ns access time, and dual chip enable (CE1/CE2) logic. It operates across three voltage ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), supports 1.0 V data retention, and features an ERR output pin for real-time single-bit error detection and correction - deployed in industrial control memory buffers requiring high reliability.

For engineers reviewing the CY7C1061GE18-15BVJXIT datasheet, CY7C1061GE18-15BVJXIT pinout, CY7C1061GE18-15BVJXIT application, or CY7C1061GE18-15BVJXIT equivalent, this page delivers verified package mapping (48-ball VFBGA, BVJXI), ECC functional behavior, dual CE timing constraints, byte-write control via BHE/BLE, and ERR pin assertion logic - all confirmed from Infineon's official Rev. *T datasheet (001-81540).

Technical Context

This SRAM implements full on-die ECC encoding/decoding for every 16-bit word using Hamming code, correcting single-bit errors without external logic. The ERR pin asserts high only during read cycles when a correctable error is detected - no automatic write-back occurs, and error status is not latched.

It supports two chip enable architectures: single CE (pin 24 in TSOP I) or dual CE (CE1/CE2, active-low/high combination), with CE1 and CE2 jointly defining chip select state. Byte write control is implemented via separate BHE (I/O8–I/O15) and BLE (I/O0–I/O7) inputs, enabling independent upper/lower byte writes without masking logic.

FAQ

Does CY7C1061GE18-15BVJXIT support automatic error correction write-back?

No. The device performs single-bit error correction during read cycles and asserts the ERR pin, but does not automatically rewrite corrected data back to the memory array. System firmware must handle any required write-back if persistent correction is needed - confirmed in Note 1 of datasheet Rev. *T.

What is the function of the NC pins in the BVJXI package?

NC (No Connect) pins - such as balls A16 and A18 in the 48-ball VFBGA - are physically present but not bonded to the die. They must remain unconnected on the PCB; routing traces or applying solder paste to these balls may cause mechanical stress or shorting risks per datasheet Figure 5 notes.

Can the ERR pin be left unconnected if ECC functionality is unused?

Yes. The ERR pin is an open-drain output; if not monitored, it should be left floating (not tied HIGH or LOW), as stated in Note 6 of the datasheet. Pull-up resistors are required only when actively reading ERR status in-system.

How does dual CE (CE1/CE2) differ from single CE in timing behavior?

Dual CE requires CE1 = LOW and CE2 = HIGH to enable the device; CE is logically defined as CE1 AND (NOT CE2). This configuration adds setup/hold timing margins versus single CE, improving noise immunity in electrically noisy industrial environments - detailed in Note 12 and Truth Table on page 16.
