Product details

Overview

S29AS016J70BHI040 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, industrial-plus temperature range (–40 °C to +105 °C), and AEC-Q100 Grade 2 qualification. It supports in-system programming via standard 1.8 V V_CC, features hardware write protection (WP#), RY/BY# status signaling, and is used for automotive firmware storage and industrial boot code retention.

For engineers reviewing the S29AS016J70BHI040 datasheet, S29AS016J70BHI040 pinout, S29AS016J70BHI040 application, or S29AS016J70BHI040 equivalent, key selection criteria include boot sector architecture flexibility, JEDEC-compliant command set, CFI support for host auto-configuration, erase suspend/resume capability, and dual FBGA package options (VBK048 and VDF048).

Technical Context

The S29AS016J70BHI040 implements a sector-erasable NOR Flash architecture with eight 8 KB and thirty-one 64 KB sectors (byte mode) or eight 4 Kword and thirty-one 32 Kword sectors (word mode). It uses Fowler-Nordheim tunneling for erase and hot electron injection for program operations, with embedded algorithms handling timing, verification, and margin checking.

It integrates hardware features including a dedicated RY/BY# pin for cycle completion detection, RESET# for state-machine reset, WP# for boot-sector lock independent of sector group protection, and automatic sleep/standby modes triggered by address stability or CE#/OE# control - all operating within 1.65–1.95 V supply range.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	16 Mbit (2,097,152 × 8-bit or 1,048,576 × 16-bit)
Access Time (t_ACC)	70 ns - enables zero-wait-state operation with high-speed microcontrollers
Supply Voltage	1.65–1.95 V - single-supply operation eliminates need for 5 V or 12 V V_PP

OE#	Output Enable	Controls output buffer; allows bus sharing without external tri-state logic
WE#	Write Enable	Controls latching of commands, addresses, and data during programming/erasing
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active program/erase cycle
RESET#	Hardware Reset	Aborts ongoing operation and returns device to read array state
WP#	Write Protect Input	Hardware lock for two outermost boot sectors, independent of software protection
BYTE#	Bus Width Select	Configures interface as x8 (BYTE# = LOW) or x16 (BYTE# = HIGH)
VCC / VSS	Power / Ground	Single 1.8 V supply; internal charge pumps generate required high voltages

Key Features

Feature	Design Value
CFI Compliance	Enables host software to auto-detect device geometry, timing, and command set without hard-coded parameters
Erase Suspend/Resume	Allows interruption of erase to service real-time read/program requests in non-erasing sectors - essential for multitasking firmware environments
Secured Silicon Sector	128-word factory-programmable region with electronic serial number for secure device identification and binding
Unlock Bypass Mode	Reduces sequential programming overhead from four to two write cycles per data word - cuts flash update time by ~50%
Hardware Sector Group Protection	Locks any combination of sectors in-system or via programmer to prevent accidental overwrite of critical boot or configuration code

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
S29GL01GP12FAIV10	1 Gbit density, 110 nm process, 100 ns access, supports 2.7–3.6 V only	Higher capacity but incompatible voltage range; requires redesign of power delivery and level-shifting	Select only when >16 Mbit capacity and wider VCC tolerance are mandatory; not drop-in compatible
MX29GL128FHT2I-70G	128 Mbit, 1.8 V, 70 ns, 64-pin TSOP; lacks Secured Silicon Sector and CFI v1.4 support	No factory-programmable ID region; limited host auto-configuration capability	Choose for cost-sensitive, non-secure applications where serial number binding is unnecessary

Compared with S29GL01GP12FAIV10 and MX29GL128FHT2I-70G, the S29AS016J70BHI040 uniquely balances automotive-grade reliability, secure identity provisioning, and JEDEC-compliant 1.8 V operation - making it optimal for safety-critical boot memory where voltage headroom, tamper resistance, and legacy compatibility are jointly constrained.

FAQ

Is S29AS016J70BHI040 pin-compatible with earlier Am29SL160C devices?

Yes - the S29AS016J70BHI040 maintains identical pinout and software command compatibility with the Am29SL160C, including sector architecture mapping and CFI structure. This backward compatibility enables drop-in replacement in existing designs without PCB or firmware changes, preserving investment in legacy hardware and software infrastructure.

What is the function of the BYTE# pin, and how does it affect data bus configuration?

The BYTE# pin selects between x8 and x16 data bus modes: when pulled LOW, DQ0–DQ7 are active for byte-wide access; when HIGH, DQ0–DQ15 operate as a full 16-bit word bus. This dual-mode capability allows flexible integration with 8-bit or 16-bit microcontrollers without external data multiplexing, reducing system component count and layout complexity.

How does the Secured Silicon Sector differ from standard Flash sectors in terms of programming and locking?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region programmed once - either at factory or by customer - and permanently locked using a unique command sequence. Unlike standard sectors, it cannot be erased or reprogrammed after locking, and contains an 8-word electronic serial number accessible only via CFI or specific unlock sequences, ensuring irreversible device identity binding.

Can Erase Suspend be used during Chip Erase operations, or only during Sector Erase?

Erase Suspend is supported only during Sector Erase operations, not Chip Erase. The device allows suspension of a sector erase to read or program another non-erasing sector, then resume the suspended erase. Chip Erase is atomic and non-interruptible - attempting Erase Suspend during chip erase results in undefined behavior and must be avoided per datasheet Section 10.7.
