Infineon Technologies S29AS016J70BFI030

Overview

S29AS016J70BFI030 from Infineon Technologies (formerly Cypress) is a 16 Mbit, 1.8 V-only boot sector Flash memory organized as 2 M × 8-bit or 1 M × 16-bit, featuring 70 ns access time, industrial-plus temperature range (–40 °C to +105 °C), AEC-Q100 Grade 2 qualification, and flexible top/bottom boot architecture for embedded firmware storage in automotive ECUs.

For engineers reviewing the S29AS016J70BFI030 datasheet, S29AS016J70BFI030 pinout, S29AS016J70BFI030 application, or S29AS016J70BFI030 equivalent, key selection criteria include single-supply 1.65–1.95 V operation, hardware sector group protection, Erase Suspend/Resume capability, CFI compliance, and FBGA-48 (VDF048) package compatibility with space-constrained automotive and industrial control designs.

Technical Context

The S29AS016J70BFI030 implements a command-register-driven state machine for Embedded Erase and Embedded Program algorithms, enabling automatic pulse-width control and margin verification during program/erase cycles. It supports both x8 and x16 bus configurations via BYTE# pin, with DQ15–DQ0 carrying word-wide data and DQ7–DQ0 byte-wide data.

Hardware features include RY/BY# for cycle completion detection, RESET# for immediate state-machine reset to read mode, and WP# for permanent protection of two outermost boot sectors. Sector architecture comprises eight 8 KB + thirty-one 64 KB sectors (byte mode) or eight 4 Kword + thirty-one 32 Kword sectors (word mode), with factory- or customer-lockable Secured Silicon Sector (128-word/256-byte).

FAQ

Is S29AS016J70BFI030 pin-compatible with earlier S29AS016J variants?

Yes - the 'BFI030' suffix denotes the VDF048 6.0 mm × 4.0 mm FBGA package with industrial-plus temperature grade (–40 °C to +105 °C). Pinout matches all S29AS016J devices in the same FBGA variant; no layout changes are needed when migrating from older S29AS016J70BFI020 or S29AS016J70BFI010 versions in the same package.

Does this device require external high-voltage programming circuitry?

No - the S29AS016J70BFI030 performs all program and erase operations using only the 1.8 V VCC supply. Internal charge pumps generate necessary high voltages; no external 12 V VPP or 5 V sources are required, simplifying PCB design and reducing bill-of-materials cost.

How is the Secured Silicon Sector accessed and programmed?

The Secured Silicon Sector is accessed via a dedicated command sequence (Enter Secured Silicon Sector command), not standard address decoding. Programming requires issuing the Unlock Bypass command followed by specific address/data patterns; once locked, it cannot be reprogrammed without factory-level access, ensuring permanent device identity.

Can Erase Suspend be used during chip-erase operations?

No - Erase Suspend is supported only for sector-erase operations. Chip-erase cannot be suspended; attempting to issue an Erase Suspend command during chip-erase has no effect and does not alter the ongoing operation. Designers must use sector-erase granularity when background read/program functionality is required.
