Product details

Overview

M58LW064D110ZA6 from STMicroelectronics is a 64 Mbit (8Mb × 8 / 4Mb × 16) uniform-block NOR Flash memory with 2.7–3.6 V single-supply operation, 110 ns random read access, 16-word write buffer, and 100,000 program/erase cycles per block. It implements JEDEC-standard command interface and CFI compliance for system-level firmware updates in embedded controllers and industrial HMI modules.

For engineers reviewing the M58LW064D110ZA6 datasheet, M58LW064D110ZA6 pinout, M58LW064D110ZA6 application, or M58LW064D110ZA6 equivalent, key selection criteria include uniform 64 KWord block architecture, VPEN-controlled erase/program enable, dual-mode STS (Ready/Busy or interrupt pulse), and TBGA64 (10 × 13 mm, 1 mm pitch) lead-free packaging for high-density PCB layouts.

Technical Context

This device uses an on-chip Program/Erase Controller to execute JEDEC-compliant commands-including Block Erase, Word/Byte Program, Write Buffer Load, and Suspend/Resume-without external timing control. Its dual-bus organization (x8/x16 selectable via BYTE pin) supports flexible microcontroller interfacing while maintaining consistent 110 ns random read timing across both modes.

The 128-bit Protection Register contains factory-programmed 64-bit unique ID and user-programmable 64-bit segment with OTP locking; block protection status persists across power cycles. STS output operates in either static Ready/Busy mode or pulsing Status mode-enabling hardware interrupt-driven firmware update flow control.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (8 Mb × 8 or 4 Mb × 16 configuration)
Supply Voltage	2.7–3.6 V for full read/program/erase operation - eliminates need for separate VPP or charge pumps
Random Read Access	110 ns - meets real-time boot code fetch latency requirements in ARM9/Cortex-M3 systems
Write Buffer Size	16 words - reduces host CPU overhead by enabling burst programming without per-word command overhead
Block Erase Endurance	100,000 cycles per block - supports field-upgradable firmware with multi-year field service life
Package	TBGA64 (10 × 13 mm, 1 mm ball pitch) - enables compact, thermally efficient layout in space-constrained industrial modules
Security Features	VPEN pin gating + non-volatile block protection + 128-bit OTP protection register - prevents unauthorized firmware modification during service or rework

Pinout & Package

TBGA64 (10 × 13 mm, 8 × 8 ball array, 1 mm pitch) package compliant with JEDEC J-STD-020B and RoHS. Lead-free soldering compatible.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address Inputs	A0 used only in x8 mode for byte selection; A1–A22 define 64 blocks (000000h–7FFFFFh) in uniform 128 KB addressing
DQ0–DQ15	Data I/O (x16) / DQ0–DQ7 (x8)	Bidirectional data path; latched on rising edge of W or first disabling edge of E0/E1/E2 - ensures deterministic command/data capture
E0, E1, E2	Chip Enables	Three independent CE inputs support multi-chip select decoding; device enabled when E0=L, E1=H, E2=L per Table 2
G	Output Enable	Controls data bus drivers during read; low-active - allows shared bus arbitration with other peripherals
W	Write Enable	Latches address/data on rising edge; primary control for command and data input timing
VPEN	Program/Erase Enable	Hardware gate: program/erase disabled if VPEN = L - provides fail-safe write protection during power ramp or noise events
STS	Status Output	Open-drain signal configurable as Ready/Busy (static) or Status pulse (interrupt) - enables CPU sleep during long erase operations
BYTE	Bus Width Select	High = x16 mode (DQ0–DQ15 active); Low = x8 mode (DQ0–DQ7 active, A0 selects upper/lower byte)
RP	Reset/Power-Down	Active-low hardware reset; also enters Auto Low Power mode when asserted - reduces standby current to 1 µA typical
VDD / VDDQ	Core & I/O Supplies	VDD = 2.7–3.6 V core; VDDQ = same range for I/O - simplifies power design with single regulator
VSS / VSSQ	Core & I/O Grounds	Separate analog/digital ground pins reduce noise coupling during high-speed read/write transitions

Key Features

Feature	Design Value
Uniform Block Architecture	64 identical 128 KB blocks - enables deterministic wear leveling and simplified flash translation layer (FTL) implementation
Write Buffer Programming	16-word buffer with 12 µs effective word programming time - cuts total 16-word write time to ~192 µs vs. 1.92 ms for sequential single-word writes
Program/Erase Suspend	Interruptible erase (to read/program other blocks) and interruptible program (to read other blocks) - supports real-time response in multitasking OS environments
CFI Compliance	JEDEC JESD68-compliant Common Flash Interface - enables auto-detection and vendor-agnostic driver support in U-Boot/Linux MTD stacks
Hardware Security Enforcement	VPEN pin + non-volatile block lock + OTP protection register - satisfies IEC 62443-3-3 SL2 requirements for secure firmware storage

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064N90TFI010	64 Mbit, 90 ns read, 3.0–3.6 V supply, PLCC56 package - no VPEN pin, no OTP protection register	Lacks hardware write-enable gating and device-unique ID; requires external logic for equivalent security	Select when cost-sensitive consumer designs prioritize speed over security and use through-hole assembly
MX29LV640EBTI-90G	64 Mbit, 90 ns read, 2.7–3.6 V, TSOP56 - supports CFI but no write buffer; 100K cycle rating applies to full chip, not per block	No suspend/resume; lower endurance consistency across blocks limits FTL efficiency in frequent-update scenarios	Choose for legacy board replacements where TSOP footprint matches and buffer-less programming is acceptable

Compared with S29GL064N90TFI010 and MX29LV640EBTI-90G, M58LW064D110ZA6 uniquely combines per-block endurance guarantee, hardware VPEN gating, and OTP-secured device identity - making it optimal for safety-certified and field-upgradable embedded systems where firmware integrity is non-negotiable.

FAQ

What is the function of the VPEN pin on M58LW064D110ZA6?

The VPEN (Program/Erase Enable) pin is a hardware safety gate: program and erase operations are physically disabled when VPEN is held low. This prevents unintended firmware modification during power-up transients, ESD events, or software faults. It must be driven high (typically via pull-up resistor) before issuing any CFI command sequence, and its state is sampled synchronously with command execution - providing deterministic hardware-level write protection independent of software state.

Does M58LW064D110ZA6 support both x8 and x16 data bus configurations?

Yes - the BYTE pin selects bus width: logic high enables x16 mode (DQ0–DQ15 active), logic low enables x8 mode (DQ0–DQ7 active, with A0 selecting upper/lower byte). Address mapping differs: x8 uses A0–A22 for 8 Mb addressing; x16 uses A1–A22 (A0 unused) for 4 Mb addressing. Both modes maintain identical 110 ns random read timing and share the same CFI query structure, allowing runtime reconfiguration in hybrid systems.

How does the STS pin operate in Status mode versus Ready/Busy mode?

In Ready/Busy mode (default), STS is a static open-drain output: low = operation in progress, high = idle/completed. In Status mode (enabled via Configure STS command), STS pulses once per completed program or block erase - serving as a hardware interrupt to wake the CPU. Pulse width is 50 ns minimum; timing is guaranteed across voltage/temperature. This eliminates polling overhead and enables precise synchronization of firmware update workflows in RTOS environments.

What is the purpose of the 128-bit Protection Register?

The 128-bit Protection Register consists of two 64-bit segments: the first is factory-programmed with a unique ST device ID (read-only), the second is user-programmable OTP memory. The user segment can be locked permanently after programming, preventing overwrite of critical keys or calibration data. Unlike block protection bits, this register survives full chip erase and is accessed via dedicated CFI commands - enabling secure storage of cryptographic keys or device-specific parameters required for regulatory compliance (e.g., FDA 21 CFR Part 11, IEC 62443).
