Product details
Overview
S29AL016J70TFA020 from Infineon Technologies (formerly Cypress) is a 16 Mbit (2M × 8-bit / 1M × 16-bit), 3.0 V-only boot sector Flash memory with 55 ns access time, AEC-Q100 Grade 1 (–40°C to +125°C) qualification, and flexible sector architecture including one 16 KB, two 8 KB, one 32 KB, and thirty-one 64 KB sectors. It operates across 2.7–3.6 V, supports in-system programming without high-voltage VPP, and is used for automotive engine control firmware storage.
For engineers reviewing the S29AL016J70TFA020 datasheet, S29AL016J70TFA020 pinout, S29AL016J70TFA020 application, or S29AL016J70TFA020 equivalent, key selection criteria include boot-block configuration (top/bottom), sector protection granularity, CFI compliance for host auto-configuration, erase suspend capability, and RY/BY# hardware status signaling.
Technical Context
This device implements JEDEC-standard single-power-supply Flash command set compatibility with embedded program/erase algorithms that internally manage pulse timing and margin verification. It uses Fowler-Nordheim tunneling for erase and hot electron injection for programming, with dedicated hardware controls including RESET#, WP#, and RY/BY# for system-level coordination.
The architecture integrates a secured silicon sector (128-word/256-byte) with factory- or customer-programmable 8-word electronic serial number, plus sector group protection enabling lock/unlock via command or hardware WP# assertion. Erase suspend/resume allows concurrent read/program in non-erasing sectors while background erase proceeds.

Pinout & Package
Package: 48-pin TSOP (TS048), 48-ball Fine-pitch BGA (VBK048), or 64-ball Fortified BGA (LAE064). This part number S29AL016J70TFA020 corresponds to the 48-pin TSOP variant with standard JEDEC pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; enables internal logic only when asserted - prevents bus contention during multi-device operation |
| OE# | Output Enable | Active-low output gate control; isolates DQ pins from bus when deasserted - eliminates need for external bus transceivers |
| WE# | Write Enable | Active-low write strobe; latches address/data on rising edge - synchronizes command sequences with microprocessor timing |
| RY/BY# | Ready/Busy Output | Open-drain status signal; low during program/erase - provides hardware interrupt for real-time operation monitoring |
| RESET# | Hardware Reset | Active-low asynchronous reset; forces device into read mode - enables safe recovery after power-up or fault conditions |
| WP# | Write Protect | Active-low boot sector lock; protects first/last 16 KB depending on top/bottom config - prevents accidental overwrites of bootloader code |
| BYTE# | Data Bus Width Select | High = x16 mode (DQ15–DQ0); low = x8 mode (DQ7–DQ0) - allows same device to serve multiple MCU data bus widths |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliance | Provides standardized register map for automatic host software detection and configuration of sector layout, timings, and command sets |
| Erase Suspend/Resume | Halts ongoing sector erase to service read/program requests in other sectors - enables true background firmware updates without halting system operation |
| Unlock Bypass Mode | Reduces program command sequence from four to two write cycles - cuts flash programming time by ~50% in high-volume production |
| Secured Silicon Sector | Factory- or customer-programmable 256-byte region with 16-byte electronic serial number - supports secure device identification and anti-cloning in automotive Tier-1 systems |
| Flexible Boot Configuration | Selectable top or bottom 16 KB boot block - accommodates diverse bootloader placement strategies across ECU platforms |

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 |
|---|---|---|---|
| S29AL016J70TFI020 | Same die, 48-pin TSOP, but rated for Industrial (–40°C to +85°C) instead of Automotive Grade 1 | Lacks AEC-Q100 qualification; unsuitable for under-hood automotive use | Select when cost-sensitive industrial control applications do not require extended temperature or automotive qualification |
| MX29LV160ETTI-70G | 16 Mbit, 3 V, 70 ns access, top-boot configuration only; no secured silicon sector or CFI support | No electronic serial number or factory-lock capability; limited host auto-configuration flexibility | Choose for legacy designs where CFI and secure ID are unnecessary and top-boot is sufficient |
Compared with S29AL016J70TFA020, the S29AL016J70TFI020 trades automotive qualification for lower cost in benign environments, while the MX29LV160ETTI-70G omits secured silicon and CFI-reducing security and host integration effort but limiting upgrade path flexibility.

FAQ
What boot configuration does S29AL016J70TFA020 support?
This part supports both top-boot and bottom-boot configurations via hardware strap options on BYTE# and A0 pins. The specific configuration is determined during manufacturing and fixed for the part number; S29AL016J70TFA020 is a top-boot variant per Infineon's ordering matrix. Boot block location affects which 16 KB sector is protected by WP#.
Does S29AL016J70TFA020 require external high-voltage programming?
No. The device performs all program and erase operations using only the standard 3.0 V supply (2.7–3.6 V range). Internal charge pumps generate required high voltages, eliminating need for external VPP or 5 V sources. This simplifies system power design and enables direct in-circuit programming via standard microcontroller GPIOs.
How is sector protection implemented on this Flash device?
Sector protection is implemented through three independent mechanisms: hardware WP# pin (protects boot sector), software command lock/unlock (sector group protection), and temporary unprotect mode. Protection status persists through power cycles, and locked sectors reject all program/erase commands until explicitly unlocked via valid command sequence or WP# deassertion.
Can S29AL016J70TFA020 be used in x8 and x16 data bus configurations?
Yes. The BYTE# pin selects bus width: high enables x16 mode (DQ15–DQ0 active), low enables x8 mode (DQ7–DQ0 active). In x8 mode, DQ15–DQ8 are tri-stated. This dual-mode capability allows one device to interface with 8-bit or 16-bit microcontrollers without redesign, reducing BOM complexity across product families.
