Product details
Overview
CY14B116M-ZSP25XI from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM with integrated real-time clock, organized as 1024 K × 16, featuring 25-ns access time, QuantumTrap nonvolatile storage, and industrial-grade operation from –40 °C to +85 °C. It delivers hands-off AutoStore on power-down using only a capacitor, supports software/hardware STORE/RECALL, and includes full RTC functions including alarm, watchdog timer, and programmable square-wave output.
For engineers reviewing the CY14B116M-ZSP25XI datasheet, CY14B116M-ZSP25XI pinout, CY14B116M-ZSP25XI application, or CY14B116M-ZSP25XI equivalent, key selection criteria include ×16 bus interface compatibility, RTC backup current (0.45 µA typical), Sleep mode support (FBGA only), dual CE configuration, and VRTCcap/VRTCbat backup source flexibility.
Technical Context
The device integrates a high-speed SRAM array (4096 × 4096) with parallel QuantumTrap nonvolatile elements, enabling simultaneous STORE/RECALL across all cells without byte-by-byte sequencing. Its control logic decouples SRAM access from nonvolatile operations-READ/WRITE are inhibited only during active STORE/RECALL cycles, preserving deterministic timing in real-time systems.
The embedded RTC uses a 32.768-kHz crystal oscillator with leap-year compensation, programmable alarm interrupts (minutes/hours/days/months), and a 12-bit calibration register for ±1 ppm accuracy adjustment. The INT pin serves triple function: alarm/wdog interrupt output, calibration signal, or user-selectable square-wave generator (1 Hz / 512 Hz / 4.096 kHz / 32.768 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1024 K × 16 organization), enabling compact 16-bit microcontroller or FPGA data buffering without external address multiplexing. |
| Access Time | 25 ns (max), supporting high-speed CPU interfaces up to 40 MHz synchronous read/write without wait states. |
| STORE Endurance | 1 million cycles to QuantumTrap cells, sufficient for daily power-cycle logging over 27 years in industrial control applications. |
| RTC Backup Current | 0.45 µA typical at VRTC = 2.0 V, allowing >10-year runtime on a single CR2032 coin cell (220 mAh). |
| VCC Operating Range | 2.7 V to 3.6 V, compatible with 3.3 V system rails and tolerant of brown-out conditions down to 2.7 V. |
| Data Retention | 20 years at +85 °C, verified under accelerated stress testing-no periodic refresh required for long-term archival storage. |
| Sleep Mode Current | 10 µA (typical), activated via ZZ pin in FBGA package only; reduces idle power by 98% vs. standby mode (750 µA). |
Pinout & Package
Package: 54-pin TSOP II (×16 configuration), RoHS-compliant, 0.5 mm pitch, 12.0 × 20.0 mm footprint. Pinout validated per Infineon datasheet 001-67786 Rev. *K, Figure 2 (54-pin TSOP II top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | Select one of 1,048,576 16-bit words; A0–A19 fully decoded-no external address latching needed. |
| DQ0–DQ15 | Bidirectional Data I/O | 16-bit parallel bus interface; BHE/ BLE enable upper/lower bytes independently for partial-word writes. |
| CE1 / CE2 | Dual Chip Enable | TSOP II uses single CE; this part uses CE1/CE2 logic (CE = CE1 LOW & CE2 HIGH) for precise multi-chip timing control. |
| HSB | Hardware STORE Busy | Open-drain status indicator: LOW during STORE; externally pulled LOW to trigger immediate nonvolatile save. |
| INT | Programmable Interrupt Output | Configurable as alarm/wdog interrupt, 512-Hz calibration signal, or selectable square-wave clock source. |
| VRTCcap / VRTCbat | RTC Backup Supply Inputs | Exclusive OR selection: VRTCcap for capacitor backup (low-cost), VRTCbat for battery backup (long-term retention). |
Key Features
| Feature | Design Value |
|---|---|
| AutoStore on Power-Down | Zero-software intervention STORE triggered by VCC drop below threshold; requires only 10 µF VCAP capacitor-no external controller or firmware overhead. |
| Software-Controlled STORE/RECALL | Issued via dedicated command sequences (not memory-mapped writes); prevents accidental nonvolatile writes during debug or exception handling. |
| RTC Alarm & Watchdog Timer | Independent programmable alarms (monthly to minute granularity) and watchdog timeout (0.125 s to 256 s) share same interrupt vector but use separate flag bits for unambiguous event identification. |
| Low-Power Sleep Mode | Activated by ZZ pin assertion; disables SRAM array clocks and RTC oscillator-only RTC calendar registers remain powered and updated. |
| QuantumTrap Nonvolatile Technology | Eliminates wear leveling, ECC, or block management logic; each SRAM cell has dedicated nonvolatile element-no write amplification or latency penalty. |
Applications
| Industrial Data Logger | Medical Device Memory |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar nvSRAM+RTC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STK14CA8-NL35I | 8-Mbit (512 K × 16), 35-ns access, no Sleep mode, RTC lacks watchdog timer and square-wave output. | Limited to lower-bandwidth metering where alarm granularity >1 hour suffices; no support for low-power wake-on-interrupt designs. | Choose when cost sensitivity outweighs RTC feature depth and 16-Mbit density is unnecessary. |
| FM3208-SG | 16-Mbit (1024 K × 16), 45-ns access, RTC supports only basic timekeeping-no alarm, watchdog, or calibration register. | Suitable for simple timestamping in PLC I/O modules but cannot replace CY14B116M-ZSP25XI in alarm-driven or calibration-critical systems. | Prefer when RTC functionality is limited to clock/calendar and SRAM speed is secondary to supply chain availability. |
Compared with STK14CA8-NL35I and FM3208-SG, CY14B116M-ZSP25XI uniquely combines 25-ns speed, full RTC feature set (alarm/watchdog/calibration/square-wave), and 1-million STORE endurance-making it the only option for high-reliability, time-critical, and low-power industrial recorders.

FAQ
What is the difference between VRTCcap and VRTCbat pins?
VRTCcap accepts a capacitor (typically 0.47 F) for short-term RTC backup during brief power interruptions; VRTCbat connects to a primary battery (e.g., CR2032) for long-term calendar retention. Only one should be populated-the other left unconnected. Internal circuitry automatically selects the active source based on voltage level and presence.
Can CY14B116M-ZSP25XI operate in ×8 mode?
No-CY14B116M is exclusively ×16-organized (1024 K × 16). The ×8 variant is CY14B116K (2048 K × 8). Pinout, address mapping (A0–A19), and data bus width (DQ0–DQ15) are fixed for ×16 operation; no configuration register or strap pin enables ×8 mode.
How does AutoStore behave during gradual VCC ramp-down?
AutoStore triggers when VCC falls below the internal voltage monitor threshold (typically 2.5 V), initiating STORE before SRAM data becomes unstable. With a 10 µF VCAP capacitor, it guarantees ≥10 ms of hold-up time-sufficient for complete 16-Mbit STORE even at worst-case temperature and process corner.
Is Sleep mode supported in the TSOP II package?
No-Sleep mode (activated via ZZ pin) is available only in the 165-ball FBGA package, as confirmed in datasheet footnote 6. The 54-pin TSOP II package (ZSP25XI) supports Standby mode (750 µA) but not Sleep mode (10 µA); ZZ pin is NC in TSOP II variants.
