Product details
Overview
CY62148GN30-45ZSXIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, operating across dual voltage ranges (2.2–3.6 V and 4.5–5.5 V), ultra-low standby current (3.5 µA typical), and automatic CE-controlled power-down. It serves as a non-volatile data buffer in portable instrumentation, battery-powered telemetry modules, and industrial PLC memory expansion.
For engineers reviewing the CY62148GN30-45ZSXIT datasheet, CY62148GN30-45ZSXIT pinout, CY62148GN30-45ZSXIT application, or CY62148GN30-45ZSXIT equivalent, key selection criteria include verified 45 ns read/write timing, dual-voltage compatibility, TSOP II package footprint, and MoBL®-optimized standby power for extended battery runtime.
Technical Context
This SRAM implements a fully asynchronous interface with independent Chip Enable (CE), Output Enable (OE), and Write Enable (WE) controls. Its architecture supports seamless memory expansion via CE daisy-chaining and automatic high-impedance I/O tri-state during deselect, write, or OE deassertion.
It features two distinct low-power states: ISB1/ISB2 standby modes triggered by CE HIGH at CMOS levels, reducing ICC to ≤8.7 µA, and data retention mode at VCC = 1.2 V with ICCDR ≤13 µA. Address range spans A0–A18 (512K words), with I/O0–I/O7 bidirectional data bus.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-45NLI | Same density, speed, and TSOP II package; 2.7–3.6 V only (no 5 V support) | Lacks dual-voltage capability-requires redesign for 5 V legacy systems | Select when design is strictly 3.3 V and cost sensitivity outweighs voltage flexibility |
| Renesas R1LV51216ASB-45SI | 45 ns access, 512K × 16 organization; requires data bus width adaptation | 16-bit interface increases throughput but demands PCB layout changes and software rework | Select when higher bandwidth justifies 16-bit bus redesign and larger footprint |
Compared with IS62WV5128BLL-45NLI and R1LV51216ASB-45SI, CY62148GN30-45ZSXIT uniquely delivers dual-voltage operation and 8-bit bus compatibility in a drop-in TSOP II footprint-reducing qualification effort for mixed-voltage industrial upgrades.

FAQ
What is the maximum clock frequency supported by CY62148GN30-45ZSXIT?
CY62148GN30-45ZSXIT is an asynchronous SRAM with no internal clock; its performance is defined by access time (45 ns) and cycle time (45 ns). Maximum effective throughput is ~22.2 MHz for consecutive reads/writes, limited only by external controller timing margins and PCB signal integrity-not by an internal oscillator or clock input.
Does CY62148GN30-45ZSXIT require external refresh circuitry?
No. As a static RAM, CY62148GN30-45ZSXIT retains data indefinitely while powered and does not require periodic refresh cycles. Data persistence during power loss depends solely on VCC decay profile and optional backup supply-not on refresh timing or DRAM-style row activation.
Can CY62148GN30-45ZSXIT operate at 3.3 V and still meet 45 ns timing?
Yes. The device is fully specified for 2.2–3.6 V operation, and all AC parameters-including tRC, tAA, and tWC-are guaranteed at 45 ns across this entire range when VCC ≥ 2.2 V and ambient temperature is within –40 °C to +85 °C per datasheet Rev. *D.
Is the ZSXIT suffix indicative of RoHS compliance and lead-free finish?
Yes. The "Z" prefix in ZSXIT denotes lead-free (Pb-free) construction per JEDEC J-STD-609, and the "IT" suffix indicates industrial temperature grade (–40 °C to +85 °C). The TSOP II package uses matte tin (Sn) termination with no lead content in solderable surfaces or internal interconnects.
