Product details
Overview
CY62167ELL-45ZXIT from Infineon Technologies (formerly Cypress) is a 16-Mbit MoBL® CMOS static RAM configurable as 1 M × 16 or 2 M × 8, operating at 45 ns access time over 4.5–5.5 V supply, with ultra-low standby current (1.5 µA typ) and active current (2.2 mA at 1 MHz), used in battery-powered embedded controllers and portable instrumentation.
For engineers reviewing the CY62167ELL-45ZXIT datasheet, CY62167ELL-45ZXIT pinout, CY62167ELL-45ZXIT application, or CY62167ELL-45ZXIT equivalent, key selection criteria include byte-selectable data width, automatic power-down on chip deselect, TTL-compatible I/O levels, and 48-pin TSOP I packaging for space-constrained PCB layouts.
Technical Context
The CY62167ELL-45ZXIT implements dual-word-width SRAM architecture with independent high-byte (BHE) and low-byte (BLE) enables, allowing selective 8-bit writes within a 16-bit bus. Its automatic power-down logic activates when CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH-reducing ICC to ≤12 µA without external control.
It supports TTL-level input thresholds (VIH ≥ 2.2 V, VIL ≤ 0.7 V) and delivers VOH ≥ 2.4 V at IOH = –1.0 mA (VCC = 4.5 V), making it compatible with legacy 5 V microcontrollers but not CMOS-only interfaces requiring VIH > 3.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1 M × 16 or 2 M × 8 configuration) |
| Access Time | 45 ns - defines maximum clock rate for synchronous read/write cycles |
| Supply Voltage | 4.5 V to 5.5 V - supports industrial-grade 5 V rails with ±10% tolerance |
| Standby Current | 1.5 µA typical - enables multi-year battery life in always-on sensor nodes |
| Active Current | 2.2 mA at 1 MHz - balances performance and power for intermittent data logging |
| Data Retention Voltage | 2.0 V minimum - allows memory state hold during brown-out or sleep mode |
| Package | 48-pin TSOP I - surface-mount, 12.0 × 20.0 mm footprint, JEDEC standard |
Pinout & Package
48-pin TSOP I package with 0.5 mm pitch; pin 1 index corner marked; BYTE pin (pin 45) must be tied to VCC for 1 M × 16 mode or VSS for 2 M × 8 mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1 M-word (16-bit) or 2 M-word (8-bit) addressing |
| I/O0–I/O7 | Data Bus (Low Byte) | Bi-directional 8-bit data path enabled by BLE; high-impedance when deselected or OE HIGH |
| I/O8–I/O15 | Data Bus (High Byte) | Bi-directional 8-bit data path enabled by BHE; unused in 2 M × 8 mode |
| CE1, CE2 | Chip Enable Controls | Two-level enable: CE1 LOW + CE2 HIGH enables device; CE1 HIGH or CE2 LOW forces standby |
| OE | Output Enable | Controls output drivers only; does not affect internal power state or write capability |
| WE | Write Enable | Active-LOW signal initiating write cycle; timing referenced to CE1/CE2 and BHE/BLE edges |
| BHE, BLE | Byte Enable Inputs | Independent 8-bit write masking; both HIGH places I/O pins in high-Z regardless of CE state |
| BYTE | Width Configuration | Pin 45: ties to VCC for 1 M × 16, VSS for 2 M × 8; determines A20 assignment and I/O pin usage |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Data Width | Single device supports either 16-bit microcontroller bus or 8-bit legacy processor interface via BYTE pin strap |
| Automatic Power-Down | Zero-software-overhead standby entry when CE/BHE/BLE inactive-no external controller required |
| TTL-Compatible I/O | Guaranteed VIH ≥ 2.2 V and VIL ≤ 0.7 V enables direct connection to 5 V MCUs without level-shifting |
| Low-Impact Memory Expansion | Dedicated CE1/CE2 and OE/WE controls simplify multi-SRAM bank decoding and interleaving |
| Data Retention at 2.0 V | Maintains stored contents during deep-sleep or backup-battery operation below nominal VCC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25616AL-10TLI | 10 ns faster (10 ns access), 3.3 V only, no BYTE pin or dual-width mode | Requires 3.3 V system design; lacks hardware-configurable bus width | Select when speed >45 ns is critical and voltage rail is fixed at 3.3 V |
| AS6C4008-55ZIN | 55 ns access, 2.7–5.5 V range, 32-pin SOP package, no BHE/BLE byte enables | Supports wider voltage range but offers only 8-bit interface and slower timing | Select for cost-sensitive, low-speed 8-bit systems where board space permits larger SOP footprint |
Compared with IS61LV25616AL-10TLI and AS6C4008-55ZIN, the CY62167ELL-45ZXIT uniquely combines 45 ns speed, 4.5–5.5 V operation, hardware-selectable 8/16-bit interface, and sub-µA standby-making it optimal for industrial portables needing flexible bus integration and extended battery runtime.

FAQ
What is the function of the BYTE pin on CY62167ELL-45ZXIT?
The BYTE pin (pin 45) configures the device's data bus width: tied to VCC enables 1 M × 16 mode (A19 used, I/O0–I/O15 active); tied to VSS enables 2 M × 8 mode (A20 used, I/O0–I/O7 active, BHE/ BLE/I/O8–I/O15 unused). This pin must be hard-wired-not dynamically controlled-during PCB layout.
Can CY62167ELL-45ZXIT interface directly with a 3.3 V microcontroller?
No. The CY62167ELL-45ZXIT requires 4.5–5.5 V supply and is specified for TTL-level inputs (VIH ≥ 2.2 V), but its outputs do not guarantee 3.3 V–compatible VOH. Direct connection risks undervoltage on high logic levels; a level translator or 5 V–tolerant MCU is required for safe interfacing.
How does automatic power-down activate, and what current does it draw?
Automatic power-down triggers when CE1 is HIGH, CE2 is LOW, or both BHE and BLE are HIGH-regardless of OE or WE state. In this mode, ICC drops to ≤12 µA (max) at VCC = 5.5 V and TA = 85 °C, with typical draw of 1.5 µA at 25 °C, enabling years of data retention on backup capacitors.
Is CY62167ELL-45ZXIT suitable for automotive applications?
The CY62167ELL-45ZXIT is rated for industrial temperature (–40 °C to +85 °C) and meets AEC-Q200 stress test requirements per Infineon's qualification documentation. While not AEC-Q100 qualified as a full automotive IC, it is widely deployed in body electronics and infotainment subsystems where industrial-grade reliability suffices.
