Infineon Technologies MB95F564KWQN-G-SNE1

Overview

MB95F564KWQN-G-SNE1 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller in the MB95560H series featuring the F2MC-8FX CPU core, 20 KB on-chip Flash memory, 496 bytes RAM, LIN-UART interface, and dual-bank Flash for concurrent read/program operations. It supports up to 16.25 MHz machine clock (via external clock input), 6-channel 8/10-bit ADC with selectable resolution, and operates across industrial temperature range (–40°C to +85°C) in a 32-pin QFN package.

For engineers reviewing the MB95F564KWQN-G-SNE1 datasheet, MB95F564KWQN-G-SNE1 pinout, MB95F564KWQN-G-SNE1 application, or MB95F564KWQN-G-SNE1 equivalent, key selection criteria include LIN bus master/slave capability, dual-operation Flash security, low-power standby modes (Stop/Sleep/Watch/Time-base), and N-ch open-drain I/O support for automotive body control and sensor interface designs.

Technical Context

The MB95F564KWQN-G-SNE1 implements the F2MC-8FX core with 136 basic instructions, 8-bit instruction width, and 1–3 byte variable-length encoding, enabling 61.5 ns minimum instruction execution at 16.25 MHz. Its clock system includes selectable main sources (external clock up to 32.5 MHz, main CR at 4–16 MHz via PLL), subclock options (32.768 kHz crystal or 50–150 kHz sub-CR), and integrated clock supervisor counter for oscillation monitoring.

Peripheral integration includes two 8/16-bit composite timers (configurable as 8-bit ×2 or 16-bit ×1), full-duplex LIN-UART with double-buffering and synchronous/asynchronous serial transfer, six external interrupt channels with edge-selectable wake-up, and hardware/software watchdog timers with sub-CR clock option for deep-standby reliability.

FAQ

What is the maximum operating frequency and corresponding machine clock speed?

The MB95F564KWQN-G-SNE1 accepts an external clock input up to 32.5 MHz, yielding a maximum machine clock frequency of 16.25 MHz. When using the main CR oscillator (4 MHz ±2%) with PLL multiplication rate of 4, the internal machine clock reaches 16 MHz. All timing-critical peripherals-including LIN-UART baud generation and composite timer intervals-are derived directly from this machine clock.

Does this MCU support LIN 2.2 physical layer compliance?

No, the MB95F564KWQN-G-SNE1 integrates a LIN-UART peripheral that implements the LIN protocol data link layer (ISO 17987-4), but requires an external LIN transceiver IC (e.g., TLE7259-3GE) for physical layer (ISO 17987-3) compliance. The UART signals (LIN_TX/LIN_RX) are CMOS-level and must be level-shifted and slew-rate controlled by the transceiver to meet bus voltage and timing requirements.

How is Flash memory security implemented?

Flash security is enforced via a write-protected security bit in the option byte area. Once programmed, this bit disables external read-out of Flash contents via on-chip debug interface and prevents unauthorized program/erase commands. Security activation is irreversible and occurs during final programming - verified by reading back the option byte after programming completes.

What are the thermal limitations of the WQFN package?

The WNP032 WQFN package has a junction-to-board thermal resistance (θ_JB) of 22°C/W and maximum junction temperature of +125°C. With 1.5 W typical power dissipation, the PCB must provide ≥4 cm² of 2-oz copper connected to the exposed thermal pad. Ambient temperature must remain ≤85°C in continuous operation to maintain reliability margin per AEC-Q100 Grade 2 requirements.
