Product details
Overview
CY15B101N-ZS60XET from Cypress Semiconductor is a 1-Mbit (64K × 16) automotive-grade ferroelectric RAM (F-RAM™) with SRAM-compatible parallel interface, –40 °C to +125 °C operation, 60 ns access time, 1013 read/write endurance, and NoDelay™ nonvolatile writes. It serves as direct drop-in replacement for 64K × 16 SRAM in engine control units requiring frequent parameter logging without battery backup.
For engineers reviewing the CY15B101N-ZS60XET datasheet, CY15B101N-ZS60XET pinout, CY15B101N-ZS60XET application, or CY15B101N-ZS60XET equivalent, key selection criteria include its guaranteed automotive-E temperature range, page-mode 30 ns cycle time, byte-select configurable 128K × 8 mode, and absence of write latency or data polling requirements.
Technical Context
The CY15B101N-ZS60XET implements a parallel asynchronous interface with CE/WE/OE control logic and dual-byte enable (UB/LB) for flexible 16-bit or 8-bit data bus configuration. Its ferroelectric memory array is organized as eight 2048-row blocks, each with four column locations, enabling true page-mode access without internal address latching overhead.
It supports both CE-initiated and WE-initiated read/write cycles, with precharge triggered by CE HIGH or A15–A2 address change. Sleep mode is entered via ZZ pin assertion, reducing standby current to 120 µA while disabling all I/O except ZZ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 1-Mbit (64K × 16), configurable as 128K × 8 using UB/LB controls |
| Access time | 60 ns - enables direct replacement of standard 64K × 16 SRAM without timing redesign |
| Endurance | 1013 read/write cycles - supports >10 years of continuous logging at 1 kHz write rate |
| Data retention | 121 years at +125 °C - eliminates need for battery backup or EEPROM wear leveling |
| Supply voltage | 2.0 V to 3.6 V - compatible with modern low-voltage automotive MCUs and power rails |
| Operating temperature | –40 °C to +125 °C (Automotive-E grade) - qualified per AEC-Q100 for under-hood applications |
| Package | 44-pin TSOP-II (400-mil) - surface-mount compatible with standard reflow profiles and automated assembly |
Pinout & Package
44-pin Thin Small Outline Package (TSOP-II), 400-mil body width, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address inputs | 16-bit address bus; A1–A0 select column within 4-word page for page-mode operation |
| DQ0–DQ15 | Data I/O lines | 16-bit bidirectional data bus; driven only when OE LOW and corresponding UB/LB asserted |
| WE | Write Enable | Falling edge initiates write; rising edge completes immediate nonvolatile store (NoDelay™) |
| CE | Chip Enable | Falling edge latches full address; device remains active while CE LOW for SRAM-like operation |
| OE | Output Enable | Controls DQ bus drive; HI-Z when HIGH to prevent bus contention and reduce system current |
| UB / LB | Byte select | Enable upper (DQ15–DQ8) or lower (DQ7–DQ0) byte; allow 8-bit bus interfacing or 128K × 8 configuration |
| ZZ | Sleep mode | LOW enters ultra-low-power sleep (120 µA); must be HIGH for normal operation or tied to VDD if unused |
| VDD / VSS | Power / Ground | Single 2.0–3.6 V supply; no separate VPP or charge pump required |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ writes | Immediate nonvolatile storage on WE rising edge - eliminates write latency, polling, and timeout handling in firmware |
| Page-mode 30 ns cycle time | Enables burst access to 4-word row with sub-30 ns consecutive reads/writes - improves logging throughput vs. standard SRAM |
| SRAM pinout compatibility | Direct 64K × 16 SRAM replacement without PCB redesign - same pin functions and timing envelope |
| Monolithic nonvolatility | No external battery, capacitor, or EEPROM controller needed - reduces BOM count and field failure modes |
| Automotive-E qualification | Guaranteed operation over –40 °C to +125 °C with AEC-Q100 stress testing - suitable for ECU, transmission, and ADAS modules |

IC Role / Device Role / Timing Role: Low-power configuration memory accessed infrequently but requiring guaranteed retention over 15+ years. Use Value: 120 µA standby current minimizes parasitic drain; 121-year retention exceeds automotive lifecycle requirements without refresh. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile parallel memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM25V10-G | 1-Mbit F-RAM, 44-pin TSOP-II, 55 ns access, 2.7–3.6 V supply | Lacks Automotive-E qualification; rated –40 °C to +85 °C only | Select for industrial or commercial systems where extended temperature is not required |
| IS61WV102416BLL-10MLI | 1-Mbit battery-backed SRAM, 44-pin TSOP-II, 10 ns access, requires external battery/capacitor | Higher reliability risk due to battery aging, leakage, and solder joint fatigue | Select only if ultra-fast 10 ns access is mandatory and battery maintenance is acceptable |
Compared with FM25V10-G and IS61WV102416BLL-10MLI, the CY15B101N-ZS60XET uniquely delivers automotive-grade temperature assurance, monolithic nonvolatility, and guaranteed 1013 endurance - eliminating battery management, refresh routines, and thermal derating concerns in safety-critical ECUs.

FAQ
Is CY15B101N-ZS60XET pin-compatible with standard 64K × 16 SRAMs?
Yes. It uses an industry-standard 44-pin TSOP-II footprint and identical pin functions (A0–A15, DQ0–DQ15, CE, WE, OE, UB, LB, VDD, VSS, ZZ). No PCB layout changes are needed for SRAM drop-in replacement, though ZZ must be tied to VDD if unused and pull-up on WE is recommended for power-cycle safety.
Does CY15B101N-ZS60XET require external hardware for nonvolatility?
No. It is a monolithic F-RAM device with built-in ferroelectric storage. Unlike battery-backed SRAM, it needs no external capacitor, battery, or charge-pump circuitry - reducing BOM cost, board area, and field failure modes related to power backup components.
What is the minimum write pulse width required for reliable operation?
The minimum WE pulse width is 30 ns for both read and write cycles. This is validated across the full –40 °C to +125 °C range and supports 33 MHz page-mode operation. The device guarantees immediate write completion on WE rising edge, with no additional timing constraints beyond standard SRAM tWC and tWP specifications.
Can CY15B101N-ZS60XET be used in 8-bit data bus configurations?
Yes. Using UB and LB pins, the device can operate in 128K × 8 mode: tie UB to VDD and LB to GND for lower-byte-only access, or vice versa for upper-byte-only. Both byte lanes may be enabled simultaneously for full 16-bit operation, providing flexible interface options for 8-bit or 16-bit microcontrollers.
