Product details
Overview
CY62148ESL-55ZAXAT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 55 ns access time, operating across dual voltage ranges (2.2–3.6 V and 4.5–5.5 V), ultra-low standby current (2.5 µA typ), and automatic CE-controlled power-down-designed for battery-sensitive portable and automotive infotainment systems.
For engineers reviewing the CY62148ESL-55ZAXAT datasheet, CY62148ESL-55ZAXAT pinout, CY62148ESL-55ZAXAT application, or CY62148ESL-55ZAXAT equivalent, key selection criteria include its dual-voltage support, MoBL™ low-power architecture, TTL-level I/O compatibility, and STSOP-32 packaging for space-constrained embedded memory expansion.
Technical Context
The CY62148ESL-55ZAXAT implements a fully static 512K × 8 memory array with complementary metal oxide semiconductor (CMOS) process technology, enabling zero-refresh operation and deterministic timing. Its control logic uses independent Chip Enable (CE), Output Enable (OE), and Write Enable (WE) inputs to manage read/write cycles and automatic power-down states.
When CE is HIGH, the device enters automatic power-down mode, reducing ICC to ≤7 µA while placing all I/Os in high-impedance state-regardless of OE or WE status. Address pins A0–A18 decode 512K locations, and I/O0–I/O7 operate bidirectionally with TTL-compatible input thresholds and CMOS output drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8) - supports byte-wide data bus interfacing without external multiplexing |
| Access Time | 55 ns - guarantees full-speed operation with microcontrollers and DSPs running at ≤18 MHz system clocks |
| VCC Range | 2.2–3.6 V and 4.5–5.5 V - enables direct integration into both modern low-voltage and legacy 5 V systems |
| Standby Current | 2.5 µA typical / 7 µA max - reduces battery drain by >99% during idle periods in portable devices |
| Active Current | 3.5 mA typical at 1 MHz - maintains low thermal load during sustained memory access in automotive ECUs |
| Data Retention Voltage | 1.5 V minimum - allows memory contents to persist during brown-out or sleep-mode battery voltage sag |
| Package | 32-pin STSOP (shrunk thin small outline package) - 11.8 × 10.0 mm footprint with 0.5 mm pitch for high-density PCB layout |
Pinout & Package
Package: 32-pin shrunk thin small outline package (STSOP), JEDEC MO-215 compliant, lead-free, surface-mountable with 0.5 mm pitch and 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting 512K-word addressing; no internal latching required |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface compatible with TTL input levels and CMOS output drive |
| CE | Chip Enable | Active-LOW enable; HIGH forces automatic power-down and high-Z I/Os regardless of OE/WE state |
| OE | Output Enable | Active-LOW control for read data output; disabled during write or when CE is HIGH |
| WE | Write Enable | Active-LOW signal initiating write cycle; overlaps with CE LOW to define write window |
| VCC | Power Supply | Supports dual voltage rails: 2.2–3.6 V or 4.5–5.5 V; not rated for 3.6–4.5 V operation |
| GND | Ground Reference | Single ground plane required; decoupling capacitor recommended within 5 mm of VCC pin |
Key Features
| Feature | Design Value |
|---|---|
| MoBL™ Ultra-Low Power Architecture | Reduces standby current to 2.5 µA typical-enables multi-week battery life in always-on sensor nodes |
| Automatic CE-Controlled Power-Down | Eliminates need for external power management logic; triggers instantly on CE HIGH with no timing overhead |
| TTL-Compatible Input Thresholds | Accepts standard 5 V TTL logic levels even at 2.2 V VCC-simplifies interface with legacy microcontrollers |
| Dual-Voltage Operation | Operates natively across 2.2–3.6 V and 4.5–5.5 V rails-avoids level-shifting in mixed-voltage systems |
| High-Speed 55 ns Access | Meets timing requirements of ARM Cortex-M4/M7 and Renesas RH850 automotive MCUs without wait states |

Equivalent & Alternatives
The following parts are listed as comparable options for similar static RAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS62WV5128BLL-55NLI | 55 ns access, 2.7–3.6 V only, 12 µA max ISB, SOIC-32 package | Lacks dual-voltage support and MoBL™ ultra-low standby; requires external voltage regulator for 5 V systems | Select when cost sensitivity outweighs voltage flexibility and standby current requirements |
| Renesas R1LV5128ASB-55D1 | 55 ns access, 2.2–3.6 V only, 5 µA max ISB, TSOP-II-32 package | No 4.5–5.5 V operation; higher thermal resistance (θJA = 62 °C/W) limits use in sealed automotive enclosures | Prefer for industrial temperature range designs where 5 V compatibility is unnecessary |
Compared with IS62WV5128BLL-55NLI and R1LV5128ASB-55D1, the CY62148ESL-55ZAXAT uniquely delivers dual-voltage operation, sub-3 µA typical standby, and automotive-grade reliability in a thermally efficient STSOP package-making it optimal for mixed-rail portable and automotive systems requiring guaranteed data retention at 1.5 V.

FAQ
Does CY62148ESL-55ZAXAT support true 5 V operation?
Yes-it operates across two discrete voltage ranges: 2.2–3.6 V and 4.5–5.5 V. Operation between 3.6 V and 4.5 V is not specified or guaranteed per datasheet Note 1. The device meets TTL input thresholds and drives CMOS outputs at 5 V, making it compatible with legacy 5 V microcontrollers without level shifters.
What happens to data during VCC brown-out below 1.5 V?
Data retention is guaranteed down to VCC = 1.5 V, with typical ICCDR of 3 µA and max 8.8 µA. Below 1.5 V, data is not assured; however, the device enters data retention mode automatically when CE is HIGH and VCC drops, preserving contents until power recovers or resets occur.
Can I leave address or control pins floating during standby?
No-per datasheet Note 9, CE must be held HIGH at CMOS level (≥VCC – 0.2 V) to achieve guaranteed ISB1/ISB2 current. Other inputs may float, but best practice is to tie unused address/control lines to GND or VCC via ≥10 kΩ resistors to prevent noise-induced wake-up or latch-up.
Is the STSOP-32 package RoHS-compliant and lead-free?
Yes-the CY62148ESL-55ZAXAT is manufactured in a lead-free, RoHS-compliant STSOP package (JEDEC MO-215), with matte tin finish on leads and halogen-free molding compound, meeting IPC/JEDEC J-STD-020D reflow profile requirements for Pb-free assembly.
