Infineon Technologies S29CD016J0PQFM010

Overview

S29CD016J0PQFM010 from Cypress Semiconductor is a 16 Mbit (512k × 32-bit) burst-mode Flash memory IC with simultaneous read/write capability across dual banks, operating at 2.5–2.75 V supply, 66 MHz max clock frequency, and featuring dual boot sector architecture for automotive firmware redundancy. It supports zero-latency concurrent operations using separate address/data buses and is qualified for extended temperature (–40 °C to +125 °C).

For engineers reviewing the S29CD016J0PQFM010 datasheet, S29CD016J0PQFM010 pinout, S29CD016J0PQFM010 application, or S29CD016J0PQFM010 equivalent, key selection criteria include simultaneous bank operation timing, VersatileI/O™ voltage range (1.65–3.6 V), CFI compliance, secured silicon sector lockability, and PQFP-80 package mechanical compatibility.

Technical Context

This device implements a dual-bank floating-gate Flash architecture fabricated in 110 nm process, enabling independent command execution in upper and lower banks without arbitration delay. Each bank uses dedicated X/Y decoders, address latches, and data gating, with hardware-controlled RY/BY# and WAIT# signals indicating real-time operational state.

It supports both asynchronous and synchronous (burst) read modes via programmable burst interface (2/4/8 double-word wrap-around), with JEDEC JC42.4–compliant command set and Common Flash Interface (CFI) query structure for host auto-configuration. Sector erase and double-word programming are managed by on-chip state machines with Data Polling bit feedback.

FAQ

What is the function of the ACC pin on S29CD016J0PQFM010?

The ACC (Acceleration) pin accepts VHH (12 V) to reduce internal erase and program times by enabling higher tunneling current in the floating-gate cells. When unused, it must be tied to VSS or VCC. This pin is required for factory programming but optional in field applications where standard timing is acceptable.

Does S29CD016J0PQFM010 support JEDEC-standard commands?

Yes, it implements the JEDEC JC42.4 standard command set for Flash memory, including autoselect, sector erase, and buffer programming commands. This ensures interoperability with industry-standard flash programmers and bootloader frameworks that rely on JEDEC-defined opcodes and response sequences.

How does the dual boot sector configuration work in practice?

The device partitions the memory array into top and bottom boot sectors (each 2k double-word), allowing independent locking and erasure. During boot, the host processor can select which sector to execute from via hardware strap or configuration register, enabling A/B firmware swapping and fail-safe recovery after corrupted updates.

Is the Secured Silicon Sector user-programmable and lockable?

Yes-the 2 kB Secured Silicon Sector can be programmed by the user with calibration data or cryptographic keys, then permanently locked either by factory fuse or via software command. Once locked, its contents cannot be read or modified, providing hardware-enforced protection against reverse engineering or tampering.
