Product details
Overview
CY62148ELL-55SXA from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, 4.5 V to 5.5 V supply range, and ultra-low standby current (2.5 µA typical). It features automatic CE-controlled power-down, TTL-compatible I/O, and is designed for battery-powered portable systems requiring reliable non-volatile data retention during sleep modes.
For engineers reviewing the CY62148ELL-55SXA datasheet, CY62148ELL-55SXA pinout, CY62148ELL-55SXA application, or CY62148ELL-55SXA equivalent, key selection criteria include industrial temperature support (–40 °C to +85 °C), TSOP II 32-pin package compatibility, 512K × 8 organization, MoBL® low-power architecture, and CE/OE/WE control interface timing compliance.
Technical Context
The device implements a full CMOS SRAM core with hierarchical decoding (row/column), sense amplifiers, and input/output buffers optimized for TTL-level interfacing. Its automatic power-down logic activates when CE is HIGH and address lines are stable, reducing ICC to sub-µA levels without external control.
Timing is governed by three critical enable signals: CE controls chip select and power state, OE enables output drivers, and WE gates write operations. All switching parameters-including tRC (45 ns), tAA (45 ns), and tPD (45 ns)-are guaranteed over industrial voltage and temperature ranges with CMOS input thresholds and TTL-output drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8) - supports byte-wide data bus architectures without external multiplexing |
| Access Time | 45 ns - enables direct interfacing with 10–15 MHz microcontrollers without wait states |
| VCC Range | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and tolerant of ±10% supply variation |
| Standby Current | 2.5 µA typical / 7 µA max (Industrial) - extends battery life in always-on portable devices |
| Active Current | 3.5 mA typical at 1 MHz - balances performance and power for intermittent data logging |
| Data Retention Voltage | 2.0 V minimum - maintains stored data during brown-out or backup-battery operation |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial and automotive-A environments |
Pinout & Package
Package: 32-pin Thin Small Outline Package (TSOP II), 12 × 20 mm body, 0.5 mm pitch, JEDEC MO-141AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| I/O0–I/O7 | Bidirectional Data Bus | 8-bit TTL-compatible data path; high-impedance when CE HIGH, OE HIGH, or WE LOW |
| CE | Chip Enable | Active-LOW primary selection signal; drives automatic power-down when HIGH |
| OE | Output Enable | Active-LOW read control; disables outputs (high-Z) when HIGH, independent of CE state |
| WE | Write Enable | Active-LOW write control; latches data on I/O pins when CE and WE both LOW |
| VCC | Power Supply | +4.5 V to +5.5 V core and I/O supply; decoupling required per JEDEC TSOP II layout guidelines |
| VSS | Ground | Reference return for all internal circuits and I/O; requires low-inductance connection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV5128AL-10TLI | 10 ns faster access (35 ns), but higher standby current (15 µA typical) and narrower VCC range (3.0–3.6 V) | Requires 3.3 V system redesign; unsuitable for 5 V legacy interfaces or battery-sag scenarios below 3.0 V | Select only for new 3.3 V designs prioritizing speed over power and voltage flexibility |
| AS6C4008-55TIN | Same 45 ns speed and 5 V operation, but SOIC-only packaging and no automatic power-down (ISB = 20 µA typical) | Lacks CE-driven low-power mode; requires external logic for sleep control and higher board area | Prefer when TSOP II footprint is unavailable and manual power sequencing is acceptable |
Compared with IS61LV5128AL-10TLI and AS6C4008-55TIN, CY62148ELL-55SXA uniquely combines 5 V tolerance, industrial temperature range, automatic CE power-down, and TSOP II packaging-making it optimal for retrofitting legacy 5 V portable systems where battery life and board space are constrained.

FAQ
Is CY62148ELL-55SXA compatible with 3.3 V systems?
No. The device requires 4.5 V to 5.5 V supply and is not rated for 3.3 V operation. Its VIH minimum is 2.2 V, but VCC must be ≥4.5 V for guaranteed functionality and timing compliance. For 3.3 V systems, consider IS61LV5128AL-10TLI or similar low-voltage SRAMs.
Does CY62148ELL-55SXA support true CMOS input levels?
No. It is specified for TTL-compatible inputs: VIH = 2.2 V min and VIL = 0.8 V max (TSOP II). It does not meet full CMOS thresholds (VIH ≥ 0.7×VCC), and interfacing with pure CMOS processors may require level translation or pull-up/pull-down adjustments per AN6081.
What is the maximum data retention time at 2.0 V VCC?
Data retention is indefinite at VCC ≥ 2.0 V as long as ambient temperature remains within specification (–40 °C to +85 °C) and CE remains HIGH. The device draws only 3 µA typical (ICCDR) in this mode, enabling multi-year retention on small backup capacitors or coin cells.
Can CY62148ELL-55SXA be used in automotive AEC-Q100 qualified designs?
The CY62148ELL-55SXA is rated for Automotive-A grade (–40 °C to +85 °C) and manufactured on qualified processes, but it is not AEC-Q100 certified. For AEC-Q100–compliant applications, Infineon offers the automotive-qualified variant CY62148ELL-55SXI with full stress testing and PPAP documentation.
