Product details
Overview
CY15V116QN-40BKXAT from Infineon is a 16 Mb automotive-grade ferroelectric RAM (F-RAM) organized as 2048K × 8, supporting SPI up to 40 MHz, operating from 1.71–1.89 V, and rated for –40°C to +85°C. It delivers instant non-volatile writes, 10¹⁴ endurance cycles, and 151-year data retention-enabling reliable logging in engine control units where flash write latency risks data loss during power interruption.
For engineers reviewing the CY15V116QN-40BKXAT datasheet, CY15V116QN-40BKXAT pinout, CY15V116QN-40BKXAT application, or CY15V116QN-40BKXAT equivalent, key selection criteria include SPI Mode 0/3 compatibility, WP pin-based hardware write protection, 24-ball FBGA footprint, deep power-down current (1.5 µA), and AEC-Q100 Grade 3 qualification for under-hood deployment.
Technical Context
The CY15V116QN-40BKXAT implements a true serial F-RAM architecture with zero-write-latency operation: each byte written at bus speed without polling, enabled by ferroelectric capacitor-based storage cells. Its memory array is addressed via 20-bit SPI opcodes followed by three address bytes, with upper 4 address bits ignored-ensuring full 2,097,152-byte access using standard SPI framing.
It integrates dual-layer write protection: hardware-level disable via active-low WP pin (when WPEN=1 in status register) and software-configurable block protection (1/4, 1/2, or full array). The device also includes dedicated 256-byte special sector F-RAM validated for survival across three reflow cycles, plus manufacturer ID, product ID, unique device ID, and user-writable 8-byte serial number registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2048K × 8), directly replaceable for 16Mb SPI flash/EEPROM in same footprint |
| Interface Speed | Up to 40 MHz SPI clock, enabling ~4 MB/s sequential write throughput without wait states |
| Write Endurance | 10¹⁴ read/write cycles - supports >27,000 writes/sec continuously for 10+ years in data logger applications |
| Data Retention | 151 years at +85°C - eliminates periodic refresh or backup power requirements in sealed modules |
| Supply Voltage | 1.71 V to 1.89 V - matches LPDDR2/LPDDR3 I/O voltage rails and automotive 1.8 V domain systems |
| Operating Temp | –40°C to +85°C, AEC-Q100 Grade 3 - qualified for passenger compartment and powertrain-adjacent locations |

Pinout & Package
24-ball fine-pitch ball grid array (FBGA) package, 4.0 mm × 4.0 mm × 0.75 mm body, 0.5 mm ball pitch, RoHS-compliant, lead-free matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable: must fall before each opcode; places device in standby (tristate SO, ignores SI/SCK) when high |
| SCK | Serial clock input | Synchronous timing reference; inputs latched on rising edge, SO driven on falling edge; supports 0–40 MHz, interruptible |
| SI | Serial data input | Opcode, address, and write data input; sampled on SCK rising edge; must be driven to valid logic level for IDD compliance |
| SO | Serial data output | Read data output; tristated except during read operations; transitions aligned to SCK falling edge |
| WP | Write protect input | Hardware lock for status register writes when WPEN=1; tied to VDD if unused per datasheet guidance |
| VDD | Power supply | 1.71–1.89 V core supply; decoupling required per layout guidelines to maintain AC timing integrity |
| VSS | Ground | System ground reference; requires low-impedance connection to minimize noise coupling into F-RAM cell sensing |
| DNU | Do Not Use | Ball marked DNU must remain unconnected or tied to VDD; no internal connection or function |
Key Features
| Feature | Design Value |
|---|---|
| Instant non-volatile write | Zero latency: data committed immediately after SI transfer-no polling, no timeout handling in firmware |
| Dedicated 256-byte special sector | Reflow-survivable F-RAM for calibration data or security keys that persist through PCB assembly and field rework |
| Multi-level write protection | Hardware (WP pin) + software (WRDI instruction + block-protection bits) prevents accidental overwrites in safety-critical contexts |
| Unique device identification | Factory-programmed 64-bit unique ID + 8-byte user-writable serial number for traceability and secure boot binding |
| Low-voltage deep power-down | 1.5 µA standby at 1.8 V enables battery-backed operation for >10 years on a single CR2032 coin cell |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial non-volatile memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY15B116QN-40BKXIT | Wider VDD range (1.8–3.6 V); identical timing, pinout, and F-RAM core; differs only in voltage spec and temp grade (Industrial vs Automotive) | Not AEC-Q100 qualified; unsuitable for under-hood or safety-critical ECU use | Select only for non-automotive industrial controllers with 3.3 V supply and no thermal or reliability certification requirement |
| AT25DF161-AU | 16 Mb SPI flash; 100k write cycles; 20 ms page program time; requires erase before write; no built-in WP pin logic | Lacks instant write, endurance, and hardware write protection; requires firmware overhead for wear leveling and polling | Consider only if cost sensitivity outweighs reliability, latency, and power constraints-and if existing flash driver stack can be reused |
Compared with CY15B116QN-40BKXIT, the CY15V116QN-40BKXAT provides guaranteed automotive qualification and tighter 1.8 V rail compatibility; versus AT25DF161-AU, it eliminates write latency, extends endurance by 10⁹×, and reduces firmware complexity through hardware-managed protection.

FAQ
Is CY15V116QN-40BKXAT pin-compatible with CY15B116QN-40BKXIT?
Yes-both share identical 24-ball FBGA package, pin assignments, SPI command set, and timing specifications. The only differences are supply voltage range (CY15V: 1.71–1.89 V; CY15B: 1.8–3.6 V) and qualification grade (AEC-Q100 Grade 3 vs Industrial). No PCB redesign is needed for voltage-domain compatible systems.
Does the WP pin require external pull-up resistors?
No-per datasheet Section 2, the WP pin has an internal pull-up. When unused, it may be left floating or tied to VDD; no external resistor is required. However, if hardware write protection is enabled (WPEN=1), WP must be actively driven LOW to allow status register modification.
Can the 256-byte special sector be used for secure key storage?
Yes-the special sector is electrically isolated and reflow-qualified, making it suitable for storing cryptographic keys or calibration hashes. While not tamper-resistant, its physical separation and guaranteed survival across solder cycles provide higher assurance than main array storage for critical immutable data.
What SPI modes does CY15V116QN-40BKXAT support, and how are they selected?
It supports SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), selected automatically by the master's clock polarity and phase configuration. No mode-setting command is required-the device detects and adapts to either mode on power-up or CS assertion, simplifying integration with diverse MCU SPI peripherals.
