Infineon Technologies S29CD016J0PQFM013

Overview

S29CD016J0PQFM013 from Cypress Semiconductor is a 16 Mbit (512k × 32-bit) 2.6 V single-supply burst-mode Flash memory with dual boot sector architecture, simultaneous read/write operation across two independent banks, and 66 MHz synchronous burst capability. It features x32 data bus, 110 nm floating gate technology, and is qualified for extended temperature (–40 °C to +125 °C) automotive applications.

For engineers reviewing the S29CD016J0PQFM013 datasheet, S29CD016J0PQFM013 pinout, S29CD016J0PQFM013 application, or S29CD016J0PQFM013 equivalent, key selection criteria include dual-bank zero-latency concurrency, VersatileI/O™ support (1.65–3.6 V), programmable burst lengths (2/4/8 double words), secured silicon sector, and hardware write protection on outermost large-bank sectors.

Technical Context

This device implements a dual-bank Flash architecture with physically separate address/data paths per bank, enabling true concurrent read and write operations without arbitration delay. Each bank supports independent command execution, with status reporting via RY/BY# and data polling bits.

The synchronous burst interface uses CLK, ADV#, and WAIT#/IND# to manage timing-critical transfers; initial clock delay is fixed at 4 cycles (40 MHz mode) or 5 cycles (66 MHz). Sector erase time is 1.0 s typical, and double-word programming takes 18 µs - both verified under VCC = 2.6 V ±0.15 V.

FAQ

What is the purpose of the ACC pin on S29CD016J0PQFM013?

The ACC (Acceleration) pin accepts VHH (12 V) to reduce internal program and erase times by accelerating charge injection into the floating gate. When unused, ACC must be tied to VSS or VCC - leaving it floating violates absolute maximum ratings and may cause erratic behavior during high-voltage operations.

Does S29CD016J0PQFM013 support Common Flash Interface (CFI)?

Yes, the device fully supports JEDEC-standard Common Flash Interface (CFI) query mode, enabling automatic identification of geometry, timing, and command set by host bootloaders. CFI table resides at address offset 0x0055, accessible after issuing the Autoselect command sequence.

How does the VersatileI/O™ feature benefit system design?

VersatileI/O™ allows independent VIO supply (1.65–3.6 V) while VCC remains at 2.6 V, enabling direct connection to 1.8 V or 3.3 V microcontrollers without level shifters. This reduces BOM count and PCB area in mixed-voltage automotive domains such as CAN-connected ECUs.

Can S29CD016J0PQFM013 operate in asynchronous mode only?

Yes - the device supports full asynchronous read/write/erase using CE#, OE#, and WE# without CLK. However, burst performance (66 MHz) and zero-latency dual-bank operation require synchronous mode with CLK, ADV#, and WAIT#/IND# signals properly configured per the timing specifications in Section 17.3 of the datasheet.
