Infineon Technologies MB95F652LPF-G-SNE2

Overview

MB95F652LPF-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 8 KB Flash, 256 bytes RAM, and integrated peripherals including dual 8/16-bit composite timers, 6-channel 8/12-bit ADC, LIN-UART, I²C (2 channels), and UART/SIO. It operates at up to 16.25 MHz machine clock using main PLL or external clock, supports four low-power standby modes, and targets embedded control in appliance motor drives and industrial sensors.

For engineers reviewing the MB95F652LPF-G-SNE2 datasheet, MB95F652LPF-G-SNE2 pinout, MB95F652LPF-G-SNE2 application, or MB95F652LPF-G-SNE2 equivalent, key selection factors include its 20-pin I/O count (17 CMOS + 3 N-ch open-drain), dual-bank Flash for concurrent read/erase, on-chip debug via 1-wire serial interface, and LIN master/slave capability with programmable baud rate.

Technical Context

The MB95F652LPF-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 1-/8-/16-bit data operations. Its clock system allows dynamic selection among main oscillation (up to 16.25 MHz), external clock (up to 32.5 MHz), main CR (4 MHz ±2%), and main CR PLL (8/10/12/16 MHz ±2%) sources.

Peripheral integration includes two configurable 8/16-bit composite timers with PWM, input capture, and PWC functions; a time-base timer with 0.256 ms–8.3 s interval range; six external interrupt channels with edge-selectable wake-up; and dual I²C interfaces supporting Standard/Fast-mode (400 kHz) plus one shared UART/SIO channel with full-duplex double buffering and NRZ format.

FAQ

What is the maximum operating frequency of the MB95F652LPF-G-SNE2?

The device achieves a maximum machine clock frequency of 16.25 MHz when using the external clock source (up to 32.5 MHz with internal divider) or main PLL clock. At this speed, minimum instruction execution time is 61.5 ns, and interrupt processing time is 0.6 µs-enabling responsive real-time control in motor and sensor applications.

Does MB95F652LPF-G-SNE2 support LIN 2.x physical layer compliance?

Yes-the integrated LIN-UART supports LIN 2.x frame formatting, programmable baud rates via dedicated reload timer, and both master and slave operation. It meets ISO 17987-4 electrical specifications when paired with a compliant LIN transceiver such as the TLE7259-3GE.

How is Flash memory protected against unauthorized access?

MB95F652LPF-G-SNE2 implements Flash memory security by locking the entire 8 KB program area after programming. Once enabled, read/write/erase access is blocked unless a specific unlock sequence is executed via the on-chip debug interface-preventing firmware extraction or tampering in deployed systems.

Can the 8/12-bit ADC operate during low-power standby modes?

No-the ADC is disabled in all four standby modes (Stop, Sleep, Watch, Time-base timer). However, external interrupts on P00–P07, P10–P13, and P60–P63 can wake the device from any standby mode, after which the ADC resumes operation within 10 µs, enabling event-triggered sensing with minimal latency.
