Product details
Overview
S29AS016J70BFA043 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 boot blocks, 70 ns access time, and industrial-plus temperature range (–40 °C to +105 °C). It supports in-system programming via standard 1.8 V VCC, features hardware write protection (WP#), Ready/Busy# signaling, and CFI compliance for host auto-configuration in embedded boot applications.
For engineers reviewing the S29AS016J70BFA043 datasheet, S29AS016J70BFA043 pinout, S29AS016J70BFA043 application, or S29AS016J70BFA043 equivalent, key selection criteria include boot sector architecture flexibility, 1.8 V single-supply operation, AEC-Q100 Grade 2 qualification, sector erase granularity (eight 8 KB + thirty-one 64 KB sectors), and support for Erase Suspend/Resume in real-time firmware updates.
Technical Context
The S29AS016J70BFA043 implements a JEDEC-compliant command-set architecture with internal state-machine control for Embedded Program and Embedded Erase algorithms. It uses Fowler-Nordheim tunneling for erase and hot electron injection for program operations, enabling 1,000,000 erase/program cycles per sector and 20-year data retention.
Its dual-bus configuration supports x8 (DQ7–DQ0) and x16 (DQ15–DQ0) modes via BYTE# pin control. Sector group protection is enforced by hardware lock bits, and temporary unprotect allows in-system code modification in previously locked boot sectors without full device unlock.

FAQ
What boot sector configuration does S29AS016J70BFA043 support?
The S29AS016J70BFA043 supports both top-boot and bottom-boot sector architectures, selectable at manufacturing. The boot block layout consists of eight 8 KB sectors adjacent to either the highest or lowest address boundary, enabling flexible firmware partitioning for primary/backup boot images and secure bootloader isolation.
Does S29AS016J70BFA043 require external high-voltage programming?
No. The S29AS016J70BFA043 performs all program and erase operations using only the 1.8 V VCC supply. Internal charge pumps generate required high voltages, eliminating need for external 5 V or 12 V VPP sources-simplifying PCB design and enabling true single-rail system integration.
How is sector protection implemented on this device?
Sector protection is implemented via hardware lock bits that disable both program and erase operations in selected sectors. Locking can be performed in-system using command sequences or via programming equipment. The WP# pin provides additional hardware-level protection for the two outermost boot sectors independent of software lock status.
Is CFI support mandatory for host compatibility?
CFI support is optional but highly recommended: it provides standardized register access to device geometry, timing parameters, and command set, enabling host software to auto-configure without hard-coded assumptions. Systems without CFI support must implement fixed command sequences and timing models, increasing porting effort across Flash variants.
