Infineon Technologies MB95F264HPFT-G-SNE2

Overview

MB95F264HPFT-G-SNE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95260H series featuring the F2MC-8FX CPU core, 20 KB on-chip Flash memory, 496 bytes RAM, LIN-UART interface, 6-channel 8/10-bit A/D converter, and dual-bank Flash for concurrent read/erase operations. It supports main clock frequencies up to 16.25 MHz (machine clock), sub-clock options including 32.768 kHz, and operates in four low-power standby modes. It is used in automotive body control modules requiring LIN communication and analog sensor interfacing.

For engineers reviewing the MB95F264HPFT-G-SNE2 datasheet, MB95F264HPFT-G-SNE2 pinout, MB95F264HPFT-G-SNE2 application, or MB95F264HPFT-G-SNE2 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash security, 16-pin TSSOP package compatibility, and support for external interrupt wake-up from stop/sleep modes.

Technical Context

The MB95F264HPFT-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 8-bit instruction width, and 1–3 byte variable-length encoding. It executes instructions in as little as 61.5 ns at 16.25 MHz machine clock and processes interrupts in 0.6 µs under the same condition.

Its clock system includes selectable main clock sources (main OSC up to 16.25 MHz, external clock up to 32.5 MHz, or main CR at 1/8/10 MHz) and sub-clock sources (32.768 kHz sub-OSC, external 32.768 kHz, or sub-CR 50–200 kHz), with a built-in clock supervisor counter to monitor main oscillator stability.

Key Specifications

Pinout & Package

MB95F264HPFT-G-SNE2 is housed in a 16-pin TSSOP (FPT-16P-M06) package with 1 mm pitch, 5 mm × 4.4 mm footprint, and exposed thermal pad. Pin assignments are defined per the MB95260H Series datasheet Section "Pin Description (MB95260H Series, 16 pins)".

FAQ

Does MB95F264HPFT-G-SNE2 support LIN 2.2 protocol natively?

Yes. The integrated LIN-UART supports LIN 2.x physical layer signaling and protocol handling in both master and slave configurations. Frame synchronization, checksum calculation, and identifier filtering are implemented in hardware, reducing CPU overhead during bus communication.

What is the maximum operating temperature range for this device?

The MB95F264HPFT-G-SNE2 is rated for industrial temperature operation from −40 °C to +85 °C. This range is validated per the Absolute Maximum Ratings and Recommended Operating Conditions tables in datasheet 002-07516 Rev. *A, page 47–49.

Can the 8/16-bit composite timer generate complementary PWM outputs?

No. The composite timer supports single-ended PWM output, input capture, and PWC (pulse width counting) but does not provide hardware-level complementary channel generation or dead-time insertion. Complementary PWM must be implemented in firmware using dual timer channels and GPIO control.

Is the Flash memory security feature enabled by default after programming?

No. Flash security must be explicitly enabled via dedicated security lock bits during programming. Once set, the lock prevents external read-out of Flash contents and disables on-chip debug access unless erased entirely. Security status is retained across power cycles and resets.
