Product details

Overview

S29AS016J70BHIF40 from Infineon Technologies (formerly Cypress) is a 16 Mbit (2 M × 8-bit / 1 M × 16-bit), 1.8 V-only boot sector Flash memory with top/bottom configurable architecture, 70 ns access time, and industrial-plus temperature range (–40 °C to +105 °C). It supports in-system programming via standard 1.8 V V_CC, features hardware write protection (WP#), Ready/Busy# status signaling, and is used for firmware storage in embedded controllers requiring reliable nonvolatile code execution.

For engineers reviewing the S29AS016J70BHIF40 datasheet, S29AS016J70BHIF40 pinout, S29AS016J70BHIF40 application, or S29AS016J70BHIF40 equivalent, key selection criteria include boot sector configuration (top/bottom), FBGA-48 (VDF048, 6.0 mm × 4.0 mm) package compatibility, AEC-Q100 Grade 2 qualification, CFI compliance, and support for Erase Suspend/Erase Resume in real-time firmware update scenarios.

Technical Context

This device implements a command-register-based state machine that executes Embedded Program and Embedded Erase algorithms-automatically timing pulse widths and verifying cell margin without external voltage pumps. It uses Fowler-Nordheim tunneling for erase and hot electron injection for program operations, enabling full 1.8 V operation without 5 V or 12 V support.

The architecture includes eight 4 Kword / 8 Kbyte boot sectors and thirty-one 32 Kword / 64 Kbyte main sectors, with independent hardware sector group protection, temporary unprotect capability, and a dedicated 128-word Secured Silicon Sector containing factory- or customer-programmable electronic serial number. BYTE# pin selects x8/x16 bus mode, and DQ15 serves dual role as data bit (x16) or LSB address (A−1, x8).

Erase Suspend/Erase Resume	Allows interruption of sector erase to read/program other sectors - enables real-time firmware patching without halting system operation
Secured Silicon Sector	128-word (256-byte) factory- or customer-lockable region with 8-word electronic serial number - provides immutable device identity for secure boot and anti-counterfeiting
Unlock Bypass Mode	Reduces program command sequence from four to two write cycles - cuts flash programming time by ~50% in high-volume production
CFI Compliance	Standardized JEDEC interface returning device geometry, voltage, and timing parameters - enables automatic host software reconfiguration across flash families
Automatic Sleep Mode	Enters after t_ACC + 30 ns of stable address - eliminates need for explicit power-down sequencing in low-power MCU applications
Hardware Sector Group Protection	Locks/unlocks sectors via WP# or command sequence - prevents accidental overwrite of boot code or calibration data during field updates

Equivalent & Alternatives

The following parts are listed as comparable options for similar boot-sector Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL016S70TFI01	16 Mbit, 3.0 V core, 70 ns access, 64-pin TSOP - higher voltage, larger package, no CFI support	Lacks CFI and Erase Suspend; requires external 3.0 V rail; unsuitable for 1.8 V SoC integration	Select only if legacy 3.0 V system design mandates pin compatibility with older Spansion devices
MX29LV160DTTI-70G	16 Mbit, 3.0 V, 70 ns, 48-pin TSOP - no AEC-Q100 qualification, no Secured Silicon Sector	Missing automotive qualification and hardware-secured identity; limited to commercial temperature range	Acceptable for cost-sensitive industrial HMI where security and extended temp are not required

Compared with S29AS016J70BHIF40, the S29GL016S70TFI01 requires higher voltage and lacks CFI-driven flexibility, while the MX29LV160DTTI-70G omits both automotive qualification and secure identity features - making the S29AS016J70BHIF40 uniquely suited for safety-critical, field-upgradable, and 1.8 V–native designs.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now owns and supports the full S29AS Flash portfolio, delivering high-reliability nonvolatile memory for automotive, industrial, and medical applications.

The S29AS series was originally developed by Cypress as a 110 nm, 1.8 V boot-sector Flash family targeting in-system programmability, secure identity, and AEC-Q100 compliance for next-generation embedded controllers.

FAQ

Is S29AS016J70BHIF40 pin-compatible with earlier Am29SL160C devices?

Yes, it is backward compatible with the 0.32 µm Am29SL160C in pinout and software command set, but manufactured on 110 nm process for improved power efficiency and reliability. The VDF048 FBGA package matches Am29SL160C's 48-ball footprint, enabling drop-in replacement in existing layouts without redesign.

What boot sector configuration does S29AS016J70BHIF40 implement?

This part number (ending in "F40") specifies bottom boot sector architecture per Cypress ordering convention: "F3" = top boot, "F4" = bottom boot. In bottom boot mode, the lowest-addressed sectors (0x000000–0x003FFF) are boot sectors, ensuring reset vector fetch from protected memory upon power-on.

Does S29AS016J70BHIF40 support both x8 and x16 data bus modes?

Yes, via the BYTE# pin: VIH configures x16 mode (DQ15–DQ0 active), VIL configures x8 mode (DQ7–DQ0 active, DQ15 repurposed as A−1 address input). This dual-mode flexibility allows integration with 8-bit microcontrollers or 16-bit DSPs without external glue logic.

How is the Secured Silicon Sector programmed and locked?

It can be programmed and locked either at the factory (permanent, unalterable) or by the customer using the Enter Secured Silicon Sector command sequence. Once locked, the 128-word region is read-only and immune to erase commands - providing tamper-resistant storage for electronic serial numbers or cryptographic keys.
