Product details
Overview
CY14B116S-BZ35XI from Infineon Technologies (formerly Cypress) is a 16-Mbit nonvolatile SRAM organized as 512K × 32, featuring QuantumTrap nonvolatile storage, 35-ns access time, and 2.7–3.6 V operation. It performs automatic STORE on power-down using an external capacitor and supports software/hardware-controlled STORE/RECALL in industrial temperature range (–40 °C to +85 °C). Used in telecom control planes requiring persistent memory without battery backup.
For engineers reviewing the CY14B116S-BZ35XI datasheet, CY14B116S-BZ35XI pinout, CY14B116S-BZ35XI application, or CY14B116S-BZ35XI equivalent, key selection criteria include ×32 bus width support, VCAP-supplied AutoStore timing, HSB signaling for STORE status, Sleep mode availability (FBGA only), and RoHS-compliant 165-ball FBGA packaging.
Technical Context
This nvSRAM integrates a fast 35-ns SRAM array with embedded QuantumTrap nonvolatile elements per cell, enabling infinite SRAM read/write cycles and 1 million STORE cycles. Data retention is guaranteed for 20 years without power.
The device supports three data widths (×8/×16/×32); CY14B116S specifically uses A0–A18 addressing and DQ0–DQ31 I/O. STORE is triggered by power loss (via VCAP), HSB pin assertion, or software command; RECALL occurs automatically at power-up or via software.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY14B116N-BZ35XI | Same density and speed, but ×16 organization (1024K × 16); uses A0–A19, DQ0–DQ15 | Requires narrower data bus and different address decoding; lower pin count (60-ball FBGA) | Select when interfacing to 16-bit microcontrollers or legacy FPGAs with limited I/O resources |
| FM16W08-250-BGAA | 4-Mbit ×8 nvSRAM (Ramtron/Fujitsu), 250 ns access, SPI interface, no HSB or VCAP | Serial interface reduces PCB routing but increases latency; no hardware STORE trigger or sleep mode | Select for space-constrained designs where 35-ns parallel access and deterministic STORE are not required |
Compared with CY14B116N-BZ35XI and FM16W08-250-BGAA, CY14B116S-BZ35XI uniquely delivers 32-bit parallel bandwidth, VCAP-assisted AutoStore with HSB feedback, and industrial FBGA packaging - making it optimal for high-throughput, fail-safe state capture in modern embedded systems.

FAQ
What is the function of the VCAP pin, and what capacitor value is required?
The VCAP pin supplies hold-up power during VCC brown-out to complete the STORE operation from SRAM to QuantumTrap nonvolatile elements. A 4.7 µF tantalum or ceramic capacitor is required, connected between VCAP and VSS, with low ESR (< 1 Ω) to ensure ≥20 ms store time at 3.0 V. This eliminates need for external batteries or supercapacitors.
Does CY14B116S-BZ35XI support automatic RECALL on power-up?
Yes - RECALL is fully automatic at power-up when VCC rises above the minimum operating voltage (2.7 V). The device restores the last stored image from QuantumTrap to SRAM before becoming accessible. Software RECALL is also supported via command sequence for controlled initialization in safety-critical boot flows.
Is Sleep mode (ZZ) functional in all package types of CY14B116S?
No - Sleep mode via the ZZ pin is only available in the 165-ball FBGA package (e.g., CY14B116S-BZ35XI). TSOP and 60-ball FBGA variants do not implement the ZZ input. When asserted LOW in supported packages, ZZ reduces ICC to 10 µA while preserving SRAM data and enabling fast wake-up.
How does the HSB pin behave during a STORE operation?
During STORE, HSB is driven LOW by the device to signal active nonvolatile write. After completion, it is driven HIGH for tHHHD (≤100 ns) with full output drive strength, then held HIGH by a weak internal pull-up. An external pull-up resistor is optional but recommended for noise immunity in electrically noisy industrial environments.
