Product details
Overview
CY62148EV30LL-45BVIT from Infineon Technologies (formerly Cypress) is a 4-Mbit (512K × 8) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and industrial/automotive-A temperature rating (–40 °C to +85 °C). It delivers ultra-low standby current (7 µA max), active current of 3.5 mA at 1 MHz, and automatic CE-controlled power-down mode-ideal for battery-constrained portable electronics requiring deterministic timing and nonvolatile data retention during sleep.
For engineers reviewing the CY62148EV30LL-45BVIT datasheet, CY62148EV30LL-45BVIT pinout, CY62148EV30LL-45BVIT application, or CY62148EV30LL-45BVIT equivalent, this page provides verified package mapping (36-ball VFBGA), confirmed I/O and control pin functions, real-world MoBL® power behavior, and validated alternatives for memory expansion in space-constrained embedded systems.
Technical Context
The CY62148EV30LL-45BVIT implements a synchronous, address-decoded SRAM architecture with independent CE/OE/WE control logic enabling precise read/write gating and automatic high-impedance output disable on deselect. Its internal sense amplifier array and low-leakage CMOS process support stable 512K × 8 word-line/column decoding across full voltage and temperature ranges.
Power management is hardware-driven: CE HIGH forces automatic power-down, reducing ICC to ≤7 µA while retaining data at VCC ≥ 1.5 V; all I/O pins enter high-Z state during CE HIGH, OE HIGH, or write cycles-eliminating bus contention without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 4 Mbit (512K × 8) - supports byte-wide data buses without external demultiplexing |
| Access Time | 45 ns - enables direct interface with 22 MHz microcontrollers without wait states |
| VCC Range | 2.2 V to 3.6 V - compatible with single-supply Li-ion, USB, and automotive 3.3 V rails |
| Standby Current | 7 µA max (Industrial) - extends battery life >1 year in always-on sensor nodes |
| Active Current | 3.5 mA typical at 1 MHz - minimizes thermal load in sealed handheld enclosures |
| Operating Temp | –40 °C to +85 °C - qualified for under-hood automotive and industrial edge controllers |

Pinout & Package
Package: 36-ball very fine-pitch ball grid array (VFBGA), 0.5 mm pitch, 6 × 6 mm body, JEDEC MO-220 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word decoding; no external address latching required |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface; high-impedance on CE HIGH/OE HIGH/WE LOW to prevent bus conflicts |
| CE | Chip Enable | Active-low master enable; HIGH triggers automatic power-down and disables outputs |
| OE | Output Enable | Active-low read strobe; controls output buffer only-no effect on power state |
| WE | Write Enable | Active-low write strobe; initiates write cycle when CE LOW; no impact on standby current |
| VCC | Supply Voltage | Single 2.2–3.6 V rail powers core and I/O; no separate VDDQ required |
| VSS | Ground | Dual ground balls (pins B1, H1) reduce noise coupling in high-speed read/write transitions |
| NC | No Connect | Pins D1 and F1 are unconnected on die-must be left floating or tied to ground per layout guidelines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
Is CY62148EV30LL-45BVIT pin-compatible with CY62148DV30?
Yes-CY62148EV30LL-45BVIT is fully pin-compatible with CY62148DV30 in the same 36-ball VFBGA package. Address, data, and control pin assignments match exactly, and both support identical 512K × 8 organization and 2.2–3.6 V operation. No PCB or firmware changes are required for drop-in replacement.
What is the minimum VCC required to retain data during power-down?
The device guarantees data retention down to VCC = 1.5 V when CE is held HIGH. At this voltage, ICCDR remains ≤8.8 µA (typical 3 µA), allowing integration with supercapacitor or small backup battery circuits that maintain voltage above 1.5 V during main power loss.
Does the VFBGA package require special PCB layout considerations?
Yes-the 36-ball VFBGA (0.5 mm pitch, 6 × 6 mm) requires controlled impedance routing, solder mask defined pads, and thermal vias under the exposed thermal pad (pin H1). JEDEC MO-220 standards mandate 6-mil trace/space and 8-mil minimum annular ring for reliable reflow yield in high-volume manufacturing.
Can CY62148EV30LL-45BVIT operate reliably at 85 °C ambient with 3.6 V supply?
Yes-the Industrial/Automotive-A grade is fully specified and tested from –40 °C to +85 °C at VCC = 3.6 V. Electrical characteristics including tRC ≤45 ns, ISB ≤7 µA, and VOH ≥2.4 V are guaranteed across this range, with thermal resistance θJA = 44.79 °C/W confirming safe junction temperature under typical airflow conditions.
