Infineon Technologies S29CD016J0PQFM113

Overview

S29CD016J0PQFM113 from Cypress Semiconductor is a 16 Mbit (512k × 32-bit) burst-mode Flash memory 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 delivers 18 µs double-word programming and 1.0 s sector erase.

For engineers reviewing the S29CD016J0PQFM113 datasheet, S29CD016J0PQFM113 pinout, S29CD016J0PQFM113 application, or S29CD016J0PQFM113 equivalent, key selection criteria include simultaneous bank operation support, VersatileI/O™ voltage range (1.65–3.6 V), CFI compliance, persistent/password sector protection, and industrial/extended temperature qualification (–40 °C to +125 °C).

Technical Context

This device implements a dual-bank floating-gate Flash architecture fabricated in 110 nm process, enabling independent read and write execution on upper and lower banks without arbitration delay. Its synchronous burst interface supports linear 2/4/8-double-word wrap-around modes, while asynchronous access maintains 54 ns tACC and 20 ns tOE.

Command execution follows JEDEC JC42.4 standard with CFI support, and hardware features include ACC-accelerated programming/erase, WP#-protected outer sectors, RY/BY# status signaling, and suspend/resume capability for both program and erase cycles.

FAQ

What is the function of the ACC pin on S29CD016J0PQFM113?

The ACC (Acceleration) pin accepts VHH (typically 12 V) to reduce internal programming and erase times by accelerating charge injection into the floating gate. When unused, ACC must be tied to VSS or VCC. This pin is not required for standard operation but cuts typical sector erase from 1.0 s to ~0.5 s and double-word programming from 18 µs to ~10 µs under accelerated conditions.

Does S29CD016J0PQFM113 support Common Flash Interface (CFI)?

Yes, S29CD016J0PQFM113 fully supports JEDEC-standard Common Flash Interface (CFI) as defined in Appendix 1 of its datasheet (Document No. 002-00948). CFI provides standardized query mode for automatic detection of device geometry, timing parameters, and command sets - enabling OS-level flash drivers and universal programming tools to identify and configure the device without hard-coded assumptions.

How does dual boot sector configuration work on this device?

The S29CD016J0PQFM113 implements top-and-bottom boot sector architecture: eight 2k double-word sectors reside at both the highest and lowest addresses of the memory map. This allows independent locking and boot vector assignment - enabling one sector to hold a primary bootloader and the other a certified fallback image, with hardware-selectable boot source via strap pins or software configuration.

Can S29CD016J0PQFM113 operate in both synchronous and asynchronous modes?

Yes - the device supports both modes. Asynchronous operation uses CE#, OE#, and WE# for standard Flash access with 54 ns tACC. Synchronous (burst) mode uses CLK, ADV#, and WAIT#/IND# to achieve high-throughput linear bursts at 66 MHz, with configurable initial latency (4- or 5-cycle). Mode selection is controlled via internal configuration register and does not require external hardware changes.
