Product details
Overview
CY15B101N-ZS60XA from Infineon Technologies (formerly Cypress) is a 1-Mbit (64K × 16) automotive-grade ferroelectric RAM (F-RAM™) with SRAM-compatible parallel interface, 60-ns access time, 1014 read/write endurance, and 151-year data retention at +85 °C - deployed in engine control units for real-time sensor logging and fault-code storage.
For engineers reviewing the CY15B101N-ZS60XA datasheet, CY15B101N-ZS60XA pinout, CY15B101N-ZS60XA application, or CY15B101N-ZS60XA equivalent, key selection criteria include NoDelay™ write capability, TSOP-II 44-pin compatibility with legacy SRAM footprints, automotive temperature range (–40 °C to +85 °C), and byte-select (UB/LB) configurability for 128K × 8 mode.
Technical Context
The CY15B101N-ZS60XA implements a parallel asynchronous interface with CE/WE/OE control logic, supporting both CE-initiated and WE-initiated read/write cycles. Its F-RAM core eliminates write latency through instantaneous polarization switching, enabling true single-cycle nonvolatile writes without polling or erase cycles.
Internally organized as eight 2048-row blocks with four column locations per row, it enables page-mode operation with 30-ns cycle time for sequential accesses within the same row. Address A15–A2 selects the row; A1–A0 selects the column; UB and LB independently enable upper/lower 8-bit data lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 1 Mbit (64K × 16), configurable as 128K × 8 using UB/LB controls - enables flexible data bus alignment without external logic. |
| Access time | 60 ns (max) - matches standard fast SRAM timing, allowing direct drop-in replacement in existing 64K × 16 designs. |
| Endurance | 1014 read/write cycles - supports continuous logging at 1 kHz for >3,170 years without wear-out failure. |
| Data retention | 151 years at +85 °C - exceeds automotive AEC-Q100 Grade 2 requirements without backup power or refresh. |
| Supply voltage | 2.0 V to 3.6 V - compatible with modern low-voltage microcontrollers and avoids level-shifting in 3.3 V systems. |
| Operating temperature | –40 °C to +85 °C (Automotive-A grade) - qualified for under-hood ECU environments without derating. |
| Active current | 7 mA (typ) - enables low-power wake-up logging in battery-supervised modules. |
| Sleep current | 120 µA (typ) - reduces quiescent draw during vehicle sleep mode while preserving nonvolatile state. |
Pinout & Package
Package: 44-pin Thin Small Outline Package (TSOP-II), 400-mil width, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address inputs | 16-bit address bus latched on CE falling edge; A1–A0 used for column selection in page mode. |
| DQ0–DQ15 | Bidirectional data bus | 16-bit parallel I/O; HI-Z when OE HIGH or UB/LB deasserted - enables byte-wise access without bus contention. |
| WE | Write Enable | Asserted LOW to initiate write; rising edge commits data to F-RAM array with zero delay - no write-complete polling required. |
| CE | Chip Enable | Falling edge latches full address; may remain LOW for multiple accesses - enables SRAM-like CE-grounded operation. |
| OE | Output Enable | Controls DQ bus drive; data appears only after access time - prevents invalid data transients on bus. |
| UB / LB | Upper/Lower byte select | Independent 8-bit lane enables; tied to GND if unused - supports 128K × 8 configuration or byte-write isolation. |
| ZZ | Sleep mode control | LOW enters ultra-low-power sleep (120 µA); must be HIGH before access - eliminates need for external power gating. |
| VDD / VSS | Power / Ground | Single 2.0–3.6 V supply; no separate VPP or backup battery - simplifies PCB layout and BOM. |
Key Features
| Feature | Design Value |
|---|---|
| NoDelay™ writes | Writes complete in same cycle as reads - eliminates firmware wait states and EEPROM-style polling loops. |
| SRAM pinout compatibility | Industry-standard 64K × 16 parallel footprint - enables hardware reuse without PCB redesign or adapter. |
| Page-mode 30-ns cycle | Four-column burst access within same row - accelerates sequential sensor data buffering by >2× vs random access. |
| Monolithic nonvolatility | No battery, capacitor, or external support circuitry - removes field failure modes associated with BBSRAM aging. |
| Automotive qualification | AEC-Q100 Grade 2 compliant - validated for vibration, thermal cycling, and humidity resistance in ECU deployments. |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile parallel memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM22L16-G from Cypress/Infineon | 2-Mbit (128K × 16), 70-ns access, same TSOP-II 44-pin package, but requires 3.0–3.6 V only. | Higher density for extended log buffers; not suitable for 2.0–2.7 V MCU interfaces. | Select when >1 Mbit capacity is needed and system VDD ≥ 3.0 V. |
| AT28HC256-90PU from Microchip | 256-Kbit EEPROM, 90-ns access, 100K write cycles, requires 5 V supply and 5–10 ms write latency. | Limited endurance and slow writes preclude high-frequency logging; incompatible with low-voltage or real-time use cases. | Only consider for cost-sensitive, low-update-rate applications where 5 V is available and latency tolerance >5 ms exists. |
Compared with FM22L16-G and AT28HC256-90PU, CY15B101N-ZS60XA uniquely delivers 1-Mbit density with sub-100-ns nonvolatile writes, 2.0 V operation, and automotive temperature compliance - making it the sole option for real-time, low-voltage, high-endurance parallel memory in ECU and ADAS subsystems.

FAQ
Is CY15B101N-ZS60XA pin-compatible with standard 64K × 16 SRAMs?
Yes - it uses an industry-standard 44-pin TSOP-II footprint with identical A0–A15, DQ0–DQ15, CE, WE, OE, and VDD/VSS pin assignments. UB and LB map to unused pins on most SRAMs and can be tied to ground, enabling true drop-in replacement without PCB modification.
Does CY15B101N-ZS60XA require external hardware for write protection?
No - it has no internal write-protect register or software lock mechanism. Protection is implemented externally via CE/WE timing control or system-level MCU firmware. The device always accepts writes when CE and WE are asserted correctly, consistent with SRAM behavior.
Can CY15B101N-ZS60XA operate at 2.0 V while maintaining full 60-ns access time?
Yes - all AC specifications including 60-ns access time and 90-ns cycle time are guaranteed over the full 2.0–3.6 V VDD range per datasheet Rev. *F, Section 6. This enables interoperability with 2.0 V–2.7 V microcontrollers without performance penalty or voltage translation.
What happens if ZZ (sleep) is asserted during an active write cycle?
The device completes the ongoing write before entering sleep mode - no data corruption occurs. However, tZZEX (exit-from-sleep delay) of 100 ns must elapse after ZZ returns HIGH before initiating the next access. This behavior is explicitly defined in the "Sleep Mode" section (page 5) of the datasheet.
