Infineon Technologies MB95F582KPF-G-SNERE2

Overview

MB95F582KPF-G-SNERE2 from Cypress Semiconductor is an 8-bit Flash microcontroller in the MB95580H Series featuring the F2MC-8FX CPU core, 8 KB Flash memory, 240 bytes RAM, LIN-UART interface, 5-channel 8/10-bit A/D converter, and single 8/16-bit composite timer - deployed in automotive body control modules for LIN-based sensor node communication and local actuation.

For engineers reviewing the MB95F582KPF-G-SNERE2 datasheet, MB95F582KPF-G-SNERE2 pinout, MB95F582KPF-G-SNERE2 application, or MB95F582KPF-G-SNERE2 equivalent, key selection criteria include LIN master/slave capability, sub-CR clock support for low-power wake-up, dual-bank Flash for concurrent read/erase, and LCC-32 package compatibility with legacy PCB footprints.

Technical Context

The MB95F582KPF-G-SNERE2 implements the F2MC-8FX core with 136 basic instructions, 1–3 byte instruction length, and 16-bit arithmetic support - enabling efficient control logic execution at up to 16.25 MHz machine clock (via external clock input). It integrates a dedicated LIN-UART with full-duplex double buffer and configurable reload timer for baud rates compliant with LIN 2.2 specification.

Its peripheral set includes one 8/16-bit composite timer supporting PWM, input capture, and interval timing; eight selectable watch prescaler intervals; four standby modes (stop, sleep, watch, time-base timer); and on-chip debug via 1-wire serial control - all operating within 2.7–5.5 V supply range and qualified for automotive ambient temperatures (−40°C to +85°C).

FAQ

Does MB95F582KPF-G-SNERE2 support LIN 2.2 protocol natively?

Yes - the integrated LIN-UART supports full LIN 2.2 functionality including master and slave modes, automatic checksum calculation, and configurable baud rates via dedicated reload timer. No external LIN transceiver is required for basic node operation, though a physical layer driver (e.g., TJA1020) must be added for bus compliance.

What is the maximum operating frequency and how is it achieved?

The MB95F582KPF-G-SNERE2 achieves a maximum machine clock frequency of 16.25 MHz using an external clock input up to 32.5 MHz. When using the main oscillation clock (crystal/resonator), the max is 8.125 MHz machine clock. The PLL is not present in this variant - clock multiplication is only available on CR-based clock sources in higher-series parts.

Is the Flash memory truly dual-bank and can it be used for live firmware updates?

Yes - the 8 KB Flash is physically divided into upper and lower banks. While executing from one bank, the other can be erased and reprogrammed using Embedded Algorithm commands. This enables safe in-field firmware updates without halting real-time control functions, provided application code manages bank switching and validation logic.

How does the low-voltage detection (LVD) function interact with standby modes?

The LVD circuit remains active in all standby modes except stop mode. In sleep, watch, and time-base timer modes, it continuously monitors VDD and triggers a reset if voltage drops below the programmed threshold (2.7 V typical). This prevents corrupted EEPROM writes or inconsistent state transitions during battery voltage sag in automotive environments.
