Infineon Technologies S29CD016J0MDGH014

Overview

S29CD016J0MDGH014 from Spansion LLC is a 16 Mbit (512K × 32-bit) 2.5–2.75 V-only CMOS burst mode Flash memory die with simultaneous read/write capability across two independent banks, 56 MHz synchronous operation, dual boot sector architecture, and VersatileI/O™ supporting 1.65–2.75 V I/O. It targets automotive infotainment head units requiring zero-latency background erase during active code execution.

For engineers reviewing the S29CD016J0MDGH014 datasheet, S29CD016J0MDGH014 pinout, S29CD016J0MDGH014 application, or S29CD016J0MDGH014 equivalent, key selection criteria include burst interface configurability (2/4/8 double-word linear/wrap), persistent/password sector protection, Secured Silicon OTP sector, and KGD-level thermal rating up to +145°C for embedded die-on-PCB integration.

Technical Context

This Known Good Die (KGD) implements a dual-bank floating gate architecture on 110 nm process, enabling true concurrent read from one bank while programming or erasing the other-eliminating system wait states. Its command set complies fully with JEDEC 42.4 and supports Common Flash Interface (CFI) for auto-configuration.

The device uses separate CE#, OE#, and WE# controls to prevent bus contention, plus dedicated ADV# and CLK pins for synchronous burst operations. VersatileI/O™ (VCCQ) decouples I/O voltage from core VCC, allowing 1.65–2.75 V signaling independent of the 2.5–2.75 V VCC supply-critical for mixed-voltage SoC interconnects.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar burst-mode Flash memory applications.

Compared with S29CD016J0MDGH014, the Cypress alternative trades thermal robustness and synchronous throughput for broader commercial availability, while the Macronix part lacks both dual-bank concurrency and KGD qualification-making it incompatible with die-on-PCB automotive integration.

Availability

S29CD016J0MDGH014 is available at Aetrix Electronics and suitable for automotive instrument clusters, ADAS camera modules, engine control unit boot ROMs, and infotainment head units requiring stable component supply across extended temperature lifecycles.

Supply support for S29CD016J0MDGH014 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Spansion LLC was a joint venture between AMD and Fujitsu specializing in NOR Flash memory, later acquired by Cypress Semiconductor in 2015 and integrated into Infineon Technologies' memory portfolio.

The S29CD-J series was designed specifically for automotive-grade known-good die applications demanding high-temperature reliability, zero-latency concurrent operation, and secure firmware update capabilities in safety-critical ECUs.

FAQ

Is S29CD016J0MDGH014 a packaged IC or bare die?

S29CD016J0MDGH014 is a Known Good Die (KGD) - an unpackaged silicon die with tested functionality and bond pads. It requires wire bonding or flip-chip mounting onto a substrate or PCB and is not supplied in any molded package such as TSOP or BGA.

What does "KGD" mean in this context, and how is it validated?

"KGD" stands for Known Good Die: each unit undergoes full functional and parametric testing at wafer level, including DC characteristics at +145°C, burst timing validation, and sector protection verification. Test data is provided per die lot, confirming compliance with the S29CD016J_KGD_A1 specification supplement.

Does this device support JEDEC-standard commands for firmware updates?

Yes - the command set is fully compliant with JEDEC Standard 42.4 for single-power-supply Flash devices. It supports standard read, program, and erase commands, plus advanced features like Unlock Bypass, Suspend/Resume, and CFI query mode for automatic driver configuration.

Can S29CD016J0MDGH014 be used in systems with 1.8 V I/O interfaces?

Yes - its VersatileI/O™ (VCCQ) feature allows VCCQ to be set between 1.65 V and 2.75 V. When powered at 1.8 V, the device drives and receives signals compatible with 1.8 V logic families without external level shifters, while maintaining full 2.5–2.75 V core operation.
