Infineon Technologies CY62148G30-45SXIT

Overview

CY62148G30-45SXIT from Infineon is a 4-MB MoBL™ ultra-low-power SRAM with embedded ECC, organized as 512K words × 8-bit. It operates at 45 ns access time across 2.2 V–3.6 V supply, delivers 3.5 µA typical standby current, and supports TTL-compatible I/Os in a 32-pin SOIC package for battery-backed memory subsystems in industrial controllers.

For engineers reviewing the CY62148G30-45SXIT datasheet, CY62148G30-45SXIT pinout, CY62148G30-45SXIT application, or CY62148G30-45SXIT equivalent, this device is selected for low-power embedded systems requiring error-corrected volatile memory with wide voltage tolerance, fast read/write cycles, and data retention down to 1.0 V.

Technical Context

This SRAM implements a synchronous, address-decoded 512K × 8-bit array with dedicated row/column decoders, sense amplifiers, and integrated ECC encoder/decoder logic. It performs single-bit error correction on read data without automatic write-back, and uses standard CMOS control signals (CE, OE, WE) for asynchronous operation.

Memory access is initiated by asserting CE LOW; reads require OE LOW with valid address, while writes require both WE and CE LOW with data present on I/O0–I/O7. All I/Os enter high-impedance state when CE is HIGH or OE is deasserted, ensuring bus isolation during deselect.

FAQ

Does CY62148G30-45SXIT support automatic error correction write-back?

No. The embedded ECC corrects single-bit errors during read operations only and does not trigger automatic write-back to the memory array. Error detection flags are not exposed externally, and correction is transparent to the host system. This design minimizes latency and power but requires higher-layer software to manage uncorrectable multi-bit errors.

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

CY62148G30-45SXIT is an asynchronous SRAM and does not use a clock signal. Its maximum sustained operation rate is determined by AC timing: for 45 ns access, the minimum cycle time is 90 ns, enabling up to 11.1 MHz random read/write throughput. Continuous burst access is limited by address setup/hold and control signal timing margins per the datasheet's AC switching characteristics table.

Can this device operate reliably at 2.0 V supply?

No. CY62148G30-45SXIT is specified only for the 2.2 V to 3.6 V operating range. At 2.0 V, parameters including access time, standby current, and VIH/VIL thresholds are outside guaranteed specifications. For sub-2.2 V operation, consider the CY62148G18 variant (1.65 V–2.2 V range), which has different speed and power ratings.

Is the 32-pin SOIC package RoHS and REACH compliant?

Yes. CY62148G30-45SXIT carries the "XIT" suffix indicating lead-free (Pb-free), RoHS-compliant packaging per EU Directive 2011/65/EU and REACH SVHC screening. The SOIC package uses matte tin terminations and complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) for standard SMT reflow profiles.
