Product details
Overview
CY14B104L-ZS20XC from Cypress Semiconductor is a 4 Mbit (512K × 8) nonvolatile SRAM with QuantumTrap® technology, functioning as a drop-in SRAM replacement with integrated nonvolatile storage. It delivers 20 ns access time, operates from 2.7 V to 3.6 V, supports hardware/software STORE and power-up RECALL, and retains data for 20 years without backup battery - used in industrial PLCs, medical data loggers, and telecom control cards where power-loss resilience is critical.
For engineers reviewing the CY14B104L-ZS20XC datasheet, CY14B104L-ZS20XC pinout, CY14B104L-ZS20XC application, or CY14B104L-ZS20XC equivalent, key selection criteria include AutoStore capacitor sizing (VCAP), HSB timing for hardware store coordination, x8 vs. x16 configuration compatibility, and STORE cycle endurance (200,000 cycles) versus infinite SRAM read/write capability.
Technical Context
The CY14B104L-ZS20XC integrates parallel SRAM and QuantumTrap nonvolatile cells per bit, enabling simultaneous STORE/RECALL across all 524,288 bytes. Its architecture decouples volatile operation from nonvolatile persistence: SRAM supports standard asynchronous read/write timing (tAA = 20 ns, tCE = 20 ns), while STORE/RECALL are atomic operations that inhibit SRAM access.
AutoStore triggers on VCC drop below VSWITCH (typ. 2.5 V), using charge stored on the external VCAP capacitor (0.1 µF recommended). Hardware STORE is initiated by driving HSB low, with tDELAY (min. 100 ns) allowing ongoing SRAM transactions to complete before nonvolatile transfer begins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit organized as 512K × 8 - matches standard 512KB byte-addressable SRAM footprint with no address/data bus widening. |
| Access Time | 20 ns (max) - enables direct interface with 50 MHz microcontrollers without wait states. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with single 3V system rails; eliminates need for dual-voltage regulators. |
| STORE Endurance | 200,000 cycles - defines maximum number of power-loss-triggered or software-initiated nonvolatile writes before wear-out. |
| Data Retention | 20 years at +85°C - guarantees data integrity over full industrial temperature lifetime without refresh or power. |
| Nonvolatile Technology | QuantumTrap® - monolithic cell-level integration eliminates discrete EEPROM/NVRAM co-location and interconnect latency. |
| AutoStore Trigger | VCC < VSWITCH (2.5 V typ.) - initiates autonomous STORE using VCAP-supplied energy, independent of host firmware intervention. |
Pinout & Package
Package: 48-ball FBGA (9 mm × 9 mm, 0.8 mm pitch), RoHS-compliant, commercial temperature range (0°C to +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Input | 19-bit address bus for 512K × 8 configuration; A0–A17 used in x16 mode (not applicable here). |
| DQ0–DQ7 | Bidirectional Data I/O | 8-bit data bus; tri-stated when OE HIGH or during STORE/RECALL to prevent bus contention. |
| WE, CE, OE | Control Inputs | Active-low write enable, chip enable, output enable - fully compliant with JEDEC-standard SRAM timing protocols. |
| VCAP | Power Supply Terminal | Connects to 0.1 µF storage capacitor; supplies regulated energy for STORE during VCC collapse - no external regulator required. |
| HSB | Hardware Store Busy | Open-drain status/output: driven LOW during STORE/RECALL; pulled LOW externally to initiate hardware STORE; internally pulled HIGH if unconnected. |
| VCC / VSS | Power / Ground | Single 3V supply domain; VSS must be low-impedance connection to system ground plane for noise immunity during STORE. |
Key Features
| Feature | Design Value |
|---|---|
| Hands-off AutoStore | Zero-firmware power-loss protection: stores SRAM contents automatically using VCAP energy when VCC drops below 2.5 V. |
| Software STORE/RECALL | 6-cycle address sequence (e.g., 0x4E38 → 0x8FC0) enables deterministic nonvolatile control without hardware signal routing. |
| Infinite SRAM Read/Write | Standard SRAM endurance - no wear leveling or erase cycles needed for volatile operation, simplifying driver development. |
| 20-Year Data Retention | Guaranteed retention at +85°C - eliminates periodic data refresh routines and supports long-deployment field equipment. |
| 48-ball FBGA Footprint | Compact 9 mm × 9 mm package with 0.8 mm pitch - suitable for space-constrained industrial PCBs with automated assembly. |
Applications
| Industrial Data Logger | Telecom Control Card |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FM24CL04-G (Cypress) | 400 kHz I²C interface, 4 Kbit density, serial access - slower, lower capacity, no parallel bus compatibility. | Used in low-pin-count microcontroller designs where SPI/I²C suffices and bandwidth < 1 MB/s is acceptable. | Select only if system lacks parallel memory bus or requires ultra-low pin count; not a drop-in replacement for CY14B104L. |
| AS1004-20PC (Analog Devices) | 20 ns access, 4 Mbit, but uses FRAM instead of QuantumTrap - unlimited STORE cycles, but 10-year retention at +85°C (vs. 20 years). | Suitable where write endurance >200K cycles is mandatory, but long-term archival reliability is secondary. | Prefer when firmware performs frequent STOREs (e.g., every second); avoid if 20-year field life is contractually required. |
Compared with FM24CL04-G and AS1004-20PC, CY14B104L-ZS20XC uniquely balances parallel SRAM speed, 20-year retention, and hands-off AutoStore - making it optimal for high-reliability industrial systems requiring zero-modification SRAM replacement.

FAQ
What is the minimum VCAP capacitance required for reliable AutoStore operation?
The CY14B104L-ZS20XC requires a minimum 0.1 µF ceramic capacitor on the VCAP pin, rated for ≥6.3 V, placed within 5 mm of the device. This value ensures sufficient energy to complete one full STORE cycle during VCC collapse from 3.0 V to 2.5 V, as verified in Cypress DC Characteristics Table (Rev. *L, page 7).
Can CY14B104L-ZS20XC be used in x16 mode?
No - CY14B104L-ZS20XC is specifically the 512K × 8 (x8) configuration variant. The x16 version is designated CY14B104N. Pinout, address mapping (A0–A18), and data bus width (DQ0–DQ7) are fixed for x8 operation; attempting x16 use will result in incorrect addressing and data corruption.
How does HSB behave during a software-initiated STORE?
During software STORE, HSB is driven LOW by the device immediately after the sixth address read (0x8FC0) and remains LOW for the entire tSTORE duration (max. 20 ms). It returns HIGH only upon successful completion, providing unambiguous hardware handshake for host firmware to resume operations.
Is the 20 ns access time guaranteed over the full commercial temperature range?
Yes - the 20 ns access time (tAA) is specified over 0°C to +70°C and VCC = 2.7 V to 3.6 V, per Absolute Maximum Ratings and DC/AC Electrical Characteristics in Document #001-07102 Rev. *L. No derating is required for commercial-temperature operation.
