FS32R274KBK2MMMR Equivalent & Substitute Parts

Part Overview

The FS32R274KBK2MMMR is a 32-bit tri-core microcontroller from NXP Semiconductors' S32R series, featuring dual e200z4 and e200z7 cores operating at 180MHz and 240MHz respectively. This embedded IC integrates 2MB of FLASH program memory, 64KB EEPROM, and 1.5MB RAM with comprehensive connectivity options including CANbus, Ethernet, FlexRay, I2C, LINbus, SPI, and ZipWire interfaces. The device is packaged in a 257-pin LFBGA (14x14mm) form factor with surface mount configuration.

The FS32R274KBK2MMMR carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Active substitute parts maintain identical core functionality while offering improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitution of the FS32R274KBK2MMMR is determined by strict equivalence across the following critical parameters:

Core Functional Parameters:

• Identical processor architecture (e200z4, e200z7 dual-core configuration)
• Matching clock speeds (180MHz, 240MHz)
• Equivalent memory configuration (2MB FLASH, 64KB EEPROM, 1.5MB RAM)
• Identical connectivity suite (CANbus, Ethernet, FlexRay, I2C, LINbus, SPI, ZipWire)
• Matching peripheral set (POR, PWM, WDT)
• Identical data converter specifications (A/D 16x12b SAR, 4x12 Sigma; D/A 1x12b)

Electrical & Environmental Parameters:

• Supply voltage range (1.19V ~ 5.5V)
• Operating temperature range (-40°C ~ 125°C)
• Internal oscillator configuration

Physical & Packaging Parameters:

• 257-pin LFBGA (14x14mm) package geometry
• Surface mount mounting type
• REACH compliance status

The substitute part FS32R274KSK2MMMR maintains complete electrical and functional equivalence while differing only in packaging format (Tape & Reel vs. bulk) and product lifecycle status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The FS32R274KSK2MMMR is the manufacturer-recommended substitute for the obsolete FS32R274KBK2MMMR. Both devices are electrically and functionally identical across all core specifications, memory architecture, connectivity interfaces, and operating parameters.

Selection Basis:

The substitute part offers Active product status, ensuring long-term availability and manufacturing support. The FS32R274KSK2MMMR carries ROHS3 compliance certification, meeting current environmental regulatory requirements. Both parts maintain identical REACH Unaffected status and export classification (ECCN 3A991A2).

The primary difference is packaging format: the substitute is supplied in Tape & Reel configuration, standard for automated assembly operations. The MSL rating difference (1 vs. 3) reflects packaging method; the substitute's MSL 3 (168 Hours) is typical for tape-and-reel delivery and does not affect device performance or reliability when handled according to standard moisture control procedures.

For new designs or production continuation, the FS32R274KSK2MMMR is the appropriate selection. For existing inventory management of the obsolete part, direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Are FS32R274KBK2MMMR and FS32R274KSK2MMMR pin-for-pin compatible?

A: Yes. Both devices use the identical 257-pin LFBGA (14x14mm) package with matching pin assignments, electrical characteristics, and signal definitions. PCB layout and footprint requirements are identical.

Q: Can I substitute FS32R274KSK2MMMR in existing designs using FS32R274KBK2MMMR?

A: Yes. The substitute part maintains complete functional and electrical equivalence. No design modifications are required. Firmware and software compatibility is preserved.

Q: What is the significance of the different MSL ratings?

A: MSL 1 (Unlimited) indicates the obsolete part has no moisture absorption restrictions. MSL 3 (168 Hours) for the substitute reflects tape-and-reel packaging and requires standard moisture control during storage and handling. This is standard industry practice and does not affect device reliability when proper handling procedures are followed.

Q: Why is the substitute part in Tape & Reel format?

A: Tape & Reel (TR) packaging is the standard delivery format for active production parts, optimized for automated assembly lines. This format improves manufacturing efficiency and reduces component handling costs.

Q: Are both parts REACH compliant?

A: Yes. Both FS32R274KBK2MMMR and FS32R274KSK2MMMR carry REACH Unaffected status, indicating compliance with REACH regulations.

Q: Does the substitute part support the same connectivity interfaces?

A: Yes. The FS32R274KSK2MMMR provides identical connectivity: CANbus, Ethernet, FlexRay, I2C, LINbus, SPI, and ZipWire. All peripheral functions (POR, PWM, WDT) and data converter specifications are unchanged.

Q: What is the inventory status of these parts?

A: FS32R274KBK2MMMR (Obsolete): 1133 Pcs available. FS32R274KSK2MMMR (Active): 787 Pcs available. For new production, the active substitute is recommended.
