Product details
Overview
CY62167EV30LL-45ZXAT from Cypress Semiconductor is an automotive-grade 16-Mbit CMOS static RAM organized as 1M × 16 or 2M × 8, operating at 45 ns access time over –40 °C to +85 °C, with 2.2–3.6 V supply and ultra-low standby current (1.5 µA typ). It serves as main data buffer in infotainment head units requiring fast, low-power, AEC-Q100-compliant memory.
For engineers reviewing the CY62167EV30LL-45ZXAT datasheet, CY62167EV30LL-45ZXAT pinout, CY62167EV30LL-45ZXAT application, or CY62167EV30LL-45ZXAT equivalent, key selection criteria include TSOP I/VFBGA package compatibility, byte-enable–controlled 8/16-bit mode configuration, automatic power-down behavior under CE/BHE/BLE control, and automotive temperature-rated active/standby current specs.
Technical Context
This SRAM implements dual chip enable (CE1/CE2) logic with independent byte enables (BHE/BLE) to support flexible 8-bit or 16-bit data bus interfacing. Its automatic power-down circuit reduces ICC by >99% when CE1 HIGH or CE2 LOW or both BHE/BLE HIGH - verified via ISB1 ≤ 12 µA at VCC(max) and TA = 85 °C.
The device supports two physical configurations: 48-pin TSOP I (with BYTE pin tied to VCC for 1M×16 or VSS for 2M×8) and 48-ball VFBGA. Address range spans A0–A19 (20-bit), enabling full 1M-word addressing in 16-bit mode or 2M-word in 8-bit mode, with I/O0–I/O15 bidirectional data lines and tristate-controlled outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 or 2M × 8) - enables flexible bus-width matching without external demux logic |
| Access Time | 45 ns - guarantees sub-22 MHz synchronous read/write timing in automotive microcontroller interfaces |
| Supply Voltage | 2.2 V to 3.6 V - compatible with 2.5 V and 3.3 V automotive domain controllers and PMIC rails |
| Standby Current | 1.5 µA typical, 12 µA max at 85 °C - meets ASIL-B system-level low-power sleep requirements |
| Operating Current | 2.2 mA typical at 1 MHz - enables battery-backed operation in telematics modules with <10 µW/MHz active power density |
| Temperature Range | –40 °C to +85 °C (Automotive-A grade) - qualified per AEC-Q100 Rev G for engine bay–adjacent placement |
| Data Retention | VDR ≥ 1.5 V, ICCDR ≤ 10 µA - sustains memory state during cold-cranking voltage dips below 2.0 V |
Pinout & Package
Available in Pb-free 48-pin TSOP I (ZXA suffix) and 48-ball VFBGA (L suffix) packages. Pin functions are identical across packages except NC and BYTE pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE1, CE2 | Dual chip enable inputs | CE1 LOW + CE2 HIGH enables memory; CE1 HIGH or CE2 LOW forces automatic power-down regardless of address activity |
| BHE, BLE | Byte high/low enable inputs | Control 16-bit I/O partitioning: BHE LOW → I/O8–I/O15 active; BLE LOW → I/O0–I/O7 active |
| OE | Output enable | OE LOW enables read data output; OE HIGH places I/O pins in high-impedance state even during valid CE/BHE/BLE window |
| WE | Write enable | WE LOW initiates write cycle; write terminates on first transition of WE, CE1, CE2, BHE, or BLE to inactive level |
| A0–A19 | Address inputs | 20-bit address bus supporting 1M-word (16-bit) or 2M-word (8-bit) addressing; no A20 in 1M×16 mode |
| I/O0–I/O15 | Bidirectional data bus | Tristate-controlled I/O lines; high-impedance when deselected, OE HIGH, BHE/BLE HIGH, or during write |
| BYTE | Bus width configuration | In TSOP I: tie to VCC for 1M×16, VSS for 2M×8; unused (NC) in VFBGA package |
Key Features
| Feature | Design Value |
|---|---|
| MoBL® Ultra-Low Power Architecture | Reduces active current to 2.2 mA at 1 MHz and standby to 1.5 µA - extends battery life in always-on vehicle subsystems |
| Automatic Power-Down Logic | Guarantees >99% ICC reduction when CE1 HIGH or CE2 LOW or both BHE/BLE HIGH - eliminates need for external power-gating circuitry |
| Configurable Data Bus Width | Single device supports 8-bit or 16-bit interface via BYTE pin or package-specific routing - simplifies BOM consolidation across ECU variants |
| Automotive Temperature Qualification | AEC-Q100 Grade 2 compliant (–40 °C to +85 °C) with tested ISB1 ≤ 12 µA at 85 °C - validated for under-hood infotainment gateway use |
| High-Noise Immunity Inputs | VIH min = 1.8 V (2.2–2.7 V VCC), VIL max = 0.7 V (TSOP I) - tolerates CAN/LIN bus–induced ground bounce in mixed-signal PCB layouts |

FAQ
What is the function of the BYTE pin on CY62167EV30LL-45ZXAT?
The BYTE pin is present only in the 48-pin TSOP I package and determines data bus width: tying BYTE to VCC configures the device as 1M × 16 SRAM, while tying BYTE to VSS configures it as 2M × 8 SRAM. In the VFBGA package, BYTE is not bonded and must be left unconnected.
How does automatic power-down activate in CY62167EV30LL-45ZXAT?
Automatic power-down activates when any of these conditions occur: CE1 HIGH, CE2 LOW, or both BHE and BLE HIGH. Under these states, ICC drops to ≤12 µA (ISB1) without requiring external control signals - verified across –40 °C to +85 °C and full VCC range.
Can CY62167EV30LL-45ZXAT operate reliably during cold-cranking voltage dips?
Yes. The device maintains data retention down to VCC = 1.5 V (VDR) with ICCDR ≤ 10 µA, satisfying ISO 16750-2 Pulse 4b requirements. Its CMOS input thresholds and low-voltage operation ensure functional stability during 6 V–9 V cranking transients.
Is the 45 ns access time guaranteed across the full automotive temperature range?
Yes. The 45 ns tRC (read cycle time) and tWC (write cycle time) are maximum specifications fully guaranteed over –40 °C to +85 °C and 2.2 V–3.6 V VCC, as confirmed in the AC switching characteristics table (page 7) of Document Number 38-05446 Rev. *Q.
