Spansion S29CD016J0MFAM113

Overview

S29CD016J0MFAM113 from Cypress Semiconductor is a 16 Mbit (512k × 32-bit) burst-mode Flash memory IC with simultaneous read/write capability across dual banks, 2.5–2.75 V single-supply operation, and 66 MHz synchronous access. It features dual boot sector architecture (top/bottom), 110 nm floating gate technology, and supports JEDEC-standard command set and Common Flash Interface (CFI) for embedded automotive firmware storage.

For engineers reviewing the S29CD016J0MFAM113 datasheet, S29CD016J0MFAM113 pinout, S29CD016J0MFAM113 application, or S29CD016J0MFAM113 equivalent, key selection criteria include simultaneous bank operation latency, VersatileI/O™ voltage range (1.65–3.6 V), burst configuration flexibility (2/4/8 double-word wrap), and extended temperature support (–40 °C to +125 °C).

Technical Context

This device implements a dual-bank architecture with independent address/data paths per bank, enabling zero-latency concurrent read from one bank while programming or erasing the other. Its synchronous burst interface uses CLK, ADV#, and WAIT#/IND# signals to coordinate finite or continuous data transfers aligned to system clock edges.

The internal state machine executes JEDEC-compliant commands-including autoselect, program, sector erase, suspend/resume-and integrates hardware protection via WP# (sector lock), ACC (high-voltage acceleration), and RY/BY# status feedback. Sector protection supports both persistent bits and password-based locking of secured silicon regions.

FAQ

What is the function of the ACC pin on S29CD016J0MFAM113?

The ACC (Acceleration) pin accepts a high-voltage signal (VHH ≈ 12 V) to accelerate internal erase and program operations by boosting internal charge pump efficiency. When unused, it must be tied to VSS or VCC. This pin reduces typical double-word programming time to 18 µs and sector erase to 1.0 s, critical for minimizing OTA update windows in automotive applications.

Does S29CD016J0MFAM113 support JEDEC-standard commands?

Yes, the device implements the JEDEC JC42.4 standard command set for autoselect, read, program, and sector erase operations. It also supports Common Flash Interface (CFI) query mode, allowing host systems to dynamically detect device geometry, timing parameters, and protection features without hard-coded assumptions.

How does the dual boot sector configuration work in practice?

The device allocates eight 2k double-word sectors at both the top and bottom of the memory map, enabling independent firmware images-one for active runtime execution and another for verified backup or pending updates. The boot sector option (0 = top, 1 = bottom) is fixed at manufacturing and determines which sector group serves as the initial boot target after reset.

Can S29CD016J0MFAM113 operate with a 1.8 V I/O interface?

Yes, its VersatileI/O™ feature supports VIO from 1.65 V to 3.6 V, permitting direct connection to 1.8 V logic without level shifters. However, VCC remains fixed at 2.5–2.75 V for core memory operation; VIO only governs input thresholds and output drive strength on DQ, CE#, OE#, WE#, and control pins.
