Product details
Overview
CY62147EV30LL-45B2XA from Infineon Technologies is a 1-Mbit (128K × 8) low-power asynchronous CMOS static RAM (SRAM) with 3.3 V supply, 45 ns access time, and industrial temperature range (–40 °C to +85 °C). It features automatic power-down mode, TTL-compatible inputs/outputs, and is used in networking control planes, industrial PLC data buffers, and legacy microcontroller-based instrumentation.
For engineers reviewing the CY62147EV30LL-45B2XA datasheet, CY62147EV30LL-45B2XA pinout, CY62147EV30LL-45B2XA application, or CY62147EV30LL-45B2XA equivalent, key selection criteria include access time consistency under variable VCC, standby current at extended temperature, bus capacitance tolerance, and compatibility with legacy 8-bit/16-bit address/data buses.
Technical Context
This SRAM implements a fully decoded asynchronous architecture with separate chip enable (CE), output enable (OE), and write enable (WE) controls-enabling flexible memory-mapped I/O and burst-free read/write cycles. It uses standard TTL-level input thresholds and drives ±2 mA at VOH/VOL under full load.
No internal refresh, parity, or error correction is included; operation relies on external address stability during CE/OE/WE assertion windows. The device supports byte-wide data access without multiplexing and maintains data integrity during brown-out conditions down to 2.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 Mbit (128K × 8): supports 128 KB of byte-addressable volatile storage without wait states |
| Supply Voltage | 3.3 V ± 0.3 V: compatible with standard 3.3 V logic domains; no 5 V tolerance |
| Access Time | 45 ns max: guarantees read data valid within 45 ns after address and CE/OE stabilization |
| Standby Current | 1 μA max at 85 °C: enables ultra-low-power retention in battery-backed systems |
| Operating Temperature | –40 °C to +85 °C: qualified for industrial environments without derating |
| Input/Output Interface | TTL-compatible: interfaces directly with legacy MCU GPIOs without level-shifting |
| Power-Down Mode | Automatic via CE high: reduces current to 1 μA without external control signals |
Pinout & Package
Supplied in a 32-pin TSOP II (Thin Small Outline Package, Type II) with 0.5 mm pitch, 11.8 mm × 10.0 mm body size, and JEDEC MO-141AC compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K word decoding; no address multiplexing |
| I/O0–I/O7 | Bi-directional Data Bus | 8-bit parallel interface; high-impedance when OE = high or CE = high |
| CE# | Chip Enable (active low) | Primary device select; places I/O pins in high-Z and activates power-down when high |
| OE# | Output Enable (active low) | Gates output drivers only; no effect on internal state or power consumption |
| WE# | Write Enable (active low) | Controls write cycle timing; must be asserted before or with address setup |
| VCC | Power Supply | 3.3 V core and I/O supply; decoupling required within 10 mm of pin |
| VSS | Ground | Digital ground reference for all signals and internal logic |
Key Features
| Feature | Design Value |
|---|---|
| Low active power dissipation | Max 25 mW at 45 ns access and 1 MHz bus toggle rate |
| Fast address-to-data access | 45 ns tAA ensures compatibility with 22 MHz CPU bus clocks |
| Automatic low-power retention | 1 μA standby current achieved solely by CE# high-no register writes needed |
| TTL-level signal compatibility | VIL ≤ 0.8 V and VIH ≥ 2.0 V allow direct connection to 3.3 V or 5 V tolerant MCUs |
| Industrial temperature qualification | Full functionality verified across –40 °C to +85 °C without timing margin reduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV102416AL-10TLI | 1 Mbit (64K × 16), 10 ns access, 3.3 V, 44-pin TSOP | Wider 16-bit bus; faster but higher power (30 mA active); no industrial temp option | Select when 16-bit data path and sub-10 ns timing are required; verify PCB footprint compatibility |
| AS6C1008-55ZIN | 1 Mbit (128K × 8), 55 ns access, 3.3 V, 32-pin SOP | Slower access; larger SOP package; 10 μA standby (10× higher than CY62147EV30LL-45B2XA) | Choose for cost-sensitive designs where 55 ns is acceptable and SOP placement simplifies assembly |
Compared with IS61LV102416AL-10TLI and AS6C1008-55ZIN, CY62147EV30LL-45B2XA uniquely balances 45 ns speed, 1 μA industrial-temp standby, and 8-bit bus alignment-making it optimal for space-constrained, battery-aware industrial controllers where timing margin and power efficiency are co-critical.

FAQ
Is CY62147EV30LL-45B2XA RoHS compliant and lead-free?
Yes, CY62147EV30LL-45B2XA is RoHS-compliant and manufactured with lead-free terminations per JEDEC J-STD-020. The TSOP II package uses matte tin plating, and the device meets IPC/JEDEC J-STD-033 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
Does this SRAM require an external clock or refresh circuitry?
No. CY62147EV30LL-45B2XA is a fully asynchronous static RAM with no clock input or refresh requirement. Data retention depends solely on stable VCC; internal latches hold state as long as supply remains above 2.0 V, even during CE#-driven power-down.
Can CY62147EV30LL-45B2XA operate at 2.7 V for ultra-low-power modes?
No. The device is specified only for 3.3 V ± 0.3 V (3.0 V to 3.6 V). Operation below 3.0 V violates datasheet limits: access time degrades beyond specification, and standby current may rise unpredictably. For sub-3.0 V operation, consider Infineon's CY62167EV30 series.
What is the maximum capacitive load the I/O pins can drive reliably?
The outputs are characterized to drive up to 30 pF load capacitance while maintaining 45 ns access time and TTL-compatible voltage levels. Exceeding 30 pF increases propagation delay and may cause setup/hold violations on high-speed buses; use series termination or buffer drivers for loads >30 pF.
