Infineon Technologies CY62147G30-45BVXIT

Overview

CY62147G30-45BVXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit MoBL® SRAM with embedded single-bit error-correcting code (ECC), organized as 256K × 16, operating at 45 ns access time across 2.2 V–3.6 V supply range. It features TTL-compatible I/Os, ERR pin for real-time ECC event indication, and ultra-low standby current (max 8.7 µA). Used in industrial control modules requiring data integrity under extended temperature cycling.

For engineers reviewing the CY62147G30-45BVXIT datasheet, CY62147G30-45BVXIT pinout, CY62147G30-45BVXIT application, or CY62147G30-45BVXIT equivalent, key selection criteria include ECC-enabled reliability, dual-chip-enable support for memory banking, voltage-flexible operation (2.2–3.6 V), and VFBGA-48 packaging for high-density PCB layouts.

Technical Context

This SRAM integrates dedicated ECC encoder/decoder logic within the memory array path, enabling on-the-fly single-bit error detection and correction during read cycles without external logic. The ERR output asserts HIGH only when a correctable error is found and corrected - no automatic write-back occurs.

It supports byte-level power-down via simultaneous deassertion of BHE and BLE, forcing immediate transition to standby mode regardless of CE state. Dual chip enable (CE1/CE2) logic enables independent bank selection in multi-SRAM systems, while 1.0-V data retention allows low-power hold modes during brown-out conditions.

FAQ

Does CY62147G30-45BVXIT support automatic error write-back after ECC correction?

No. The device performs single-bit error correction during read cycles but does not automatically write the corrected data back to the memory array. Firmware must explicitly initiate a write cycle if persistent correction is required. This behavior is documented in Note 1 of the datasheet and confirmed in the functional description section.

What is the function of the ERR pin, and how is it electrically driven?

The ERR pin is an open-drain output that asserts HIGH for one clock cycle whenever a single-bit error is detected and corrected during a read access. It requires an external pull-up resistor (typically 4.7 kΩ to VCC) and is only present on "E"-suffix variants like this part. Its timing aligns with the OE-controlled read window, as shown in Figure 16 of the datasheet.

Can CY62147G30-45BVXIT operate at 1.8 V?

No. This variant (G30 suffix) is rated for 2.2 V–3.6 V only. The 1.65 V–2.2 V range applies only to CY62147G18 variants. Attempting operation below 2.2 V may result in timing violations, increased ICC, or ECC failure - per Table 1 in the datasheet's Product Portfolio section.

Is the VFBGA-48 package of CY62147G30-45BVXIT compatible with standard reflow profiles?

Yes. The package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard Pb-free reflow profiles with peak temperature ≤260 °C. Board layout must observe 0.5-mm ball pitch, 0.3-mm solder mask defined pads, and thermal relief on VCC/VSS balls per Infineon's package drawing 00-80049.
