Infineon Technologies CY62136FV30LL-45BVXIT

Overview

CY62136FV30LL-45BVXIT from Cypress Semiconductor is a 2-Mbit (128 K × 16) CMOS static RAM with 45 ns access time, 2.2–3.6 V supply range, and ultra-low standby current (1 µA typical). It supports industrial/automotive-A temperature range (–40 °C to +85 °C) and features automatic power-down on deselect, byte-wide write enable (BHE/ BLE), and high-impedance I/O during disable - deployed in battery-powered portable electronics requiring deterministic timing and low quiescent power.

For engineers reviewing the CY62136FV30LL-45BVXIT datasheet, CY62136FV30LL-45BVXIT pinout, CY62136FV30LL-45BVXIT application, or CY62136FV30LL-45BVXIT equivalent, key selection criteria include verified 45 ns read cycle time, validated 1 µA ISB2 standby current at 3.6 V, confirmed 48-ball VFBGA package mapping, and functional compatibility with CY62136V and CY62136EV30 for memory expansion in space-constrained embedded systems.

Technical Context

The CY62136FV30LL-45BVXIT implements a fully static 128K × 16 SRAM array with dual-byte write control via independent BHE and BLE inputs, enabling selective 8-bit writes without masking logic. Its CMOS architecture delivers deterministic 45 ns tRC and tAA timing under industrial voltage (2.2–3.6 V) and temperature (–40 °C to +85 °C) conditions.

Power management is handled through CE-driven automatic power-down: when CE is HIGH and address lines are stable, ISB1 drops to ≤5 µA; full deselection (CE HIGH, OE HIGH, BHE/ BLE HIGH) forces ISB2 ≤5 µA while placing all I/Os into high-Z state - critical for MoBL®-targeted portable applications where >99% power reduction during idle is required.

FAQ

What is the maximum operating frequency supported by CY62136FV30LL-45BVXIT?

The device does not operate at a clock frequency but supports a minimum read cycle time (tRC) of 45 ns, corresponding to a maximum effective throughput of approximately 22.2 MHz for consecutive reads. This timing is guaranteed across the full industrial temperature range (–40 °C to +85 °C) and 2.2–3.6 V supply, with no internal clock generator or PLL circuitry present.

Does CY62136FV30LL-45BVXIT require external pull-up resistors on BHE and BLE pins?

No external pull-ups are required. BHE and BLE are CMOS-compatible inputs with VIH(min) = 1.8 V (at VCC ≥ 2.2 V) and VIL(max) = 0.6 V. They must be driven to valid logic levels (not left floating) to meet ISB1/ISB2 specifications, but standard microcontroller GPIOs or FPGA outputs can directly drive them without passive components.

Can CY62136FV30LL-45BVXIT retain data at 1.5 V supply?

Yes - data retention is specified down to VDR = 1.5 V, with ICCDR ≤4 µA at that voltage. The device enters data retention mode automatically when CE is HIGH and VCC remains ≥1.5 V; no additional control signals or sequencing is needed beyond maintaining CE HIGH and stable VCC.

Is the 48-ball VFBGA footprint compatible with standard reflow soldering processes?

Yes - the package complies with JEDEC MO-276 and supports standard lead-free reflow profiles (peak temperature 260 °C, 60-second dwell). Its 0.5 mm pitch and dual-row ball layout are compatible with Class 7 placement accuracy and stencil-defined solder paste deposition, achieving >99.9% first-pass yield in certified SMT lines.
