Infineon Technologies CY7C1061G18-15BVJXIT

Overview

CY7C1061G18-15BVJXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit (1M × 16-bit) CMOS static RAM with embedded single-bit error-correcting code (ECC), operating at 15 ns access time, 1.65–2.2 V supply, and featuring ERR output indication for corrected errors. It supports dual chip enable (CE1/CE2), byte-level writes via BHE/BLE, and is qualified for industrial temperature range (–40 °C to +85 °C).

For engineers reviewing the CY7C1061G18-15BVJXIT datasheet, CY7C1061G18-15BVJXIT pinout, CY7C1061G18-15BVJXIT application, or CY7C1061G18-15BVJXIT equivalent, this device delivers deterministic ECC correction in high-reliability SRAM applications where data integrity is critical - especially in aerospace avionics, industrial PLCs, medical imaging buffers, and telecom baseband memory subsystems.

Technical Context

This SRAM implements on-die ECC logic that detects and corrects single-bit errors during read cycles without requiring external logic or software intervention. The ERR pin asserts high upon successful correction, enabling system-level fault logging and diagnostics.

It supports three distinct V_CC ranges (1.65–2.2 V, 2.2–3.6 V, 4.5–5.5 V), with the -15BVJXIT variant specifically rated for 15 ns t_AA at 1.65–2.2 V. Its dual CE architecture allows flexible memory mapping in multi-bank systems, while BHE/BLE enables independent upper/lower byte writes to 16-bit data bus.

FAQ

Does CY7C1061G18-15BVJXIT support automatic error write-back after correction?

No. This device performs single-bit error detection and correction during read cycles but does not automatically write the corrected data back to the memory array. The corrected value appears only on the I/O bus; any persistent correction requires external logic or host processor action. This behavior is explicitly documented in Note 1 of the datasheet.

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

NC (No Connect) pins in the 48-ball VFBGA package - such as balls C1, H1, and others shown in Figures 1 and 5 - are physically present but not bonded to the die. They serve mechanical stability and thermal dissipation roles but carry no electrical signal. Per datasheet Note 4, they must remain unconnected in PCB layout.

Can CY7C1061G18-15BVJXIT operate reliably at 1.65 V with full 15 ns timing?

Yes. The -15BVJXIT speed grade is fully characterized and guaranteed for t_AA ≤ 15 ns across the entire 1.65–2.2 V V_CC range, including at the minimum 1.65 V supply. DC and AC parameters - including VOH, VOL, and setup/hold times - are specified and tested at V_CC = 1.65 V per the Operating Range table on page 7.

How is the ERR pin used in system-level error handling?

The ERR pin is an open-drain output that drives HIGH during a single-bit correction event in a read cycle. It remains asserted for the duration of the read access (t_RC). System designers connect it to an interrupt controller or GPIO with external pull-up; no debouncing or latching is required, as the pulse width matches the read cycle timing.
