Infineon Technologies MB95F652EPFT-G-SNE2

Overview

MB95F652EPFT-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 timers, 6-channel 8/12-bit ADC, LIN-UART, I²C, and UART/SIO. It operates at up to 16.25 MHz machine clock (from external 32.5 MHz source), supports four low-power standby modes, and targets embedded control in appliance motor drives and industrial sensors.

For engineers reviewing the MB95F652EPFT-G-SNE2 datasheet, MB95F652EPFT-G-SNE2 pinout, MB95F652EPFT-G-SNE2 application, or MB95F652EPFT-G-SNE2 equivalent, key selection criteria include its 21-pin I/O count (17 CMOS + 4 N-ch open-drain), on-chip debug via 1-wire serial interface, Flash security lock, and dual-bank simultaneous read/program capability for robust firmware updates.

Technical Context

The MB95F652EPFT-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 flexible sourcing: main oscillation (≤16.25 MHz), external clock (≤32.5 MHz), or CR-based PLL (8/10/12/16 MHz ±2%).

Peripheral integration includes a configurable 8/16-bit composite timer (2 channels), time-base timer (0.256 ms–8.3 s range), hardware/software watchdog, and dual I²C interfaces - one of which shares functionality with the UART/SIO channel, enabling dynamic protocol switching in resource-constrained designs.

FAQ

Does MB95F652EPFT-G-SNE2 support LIN 2.2 protocol natively?

Yes. The integrated LIN-UART peripheral supports both master and slave roles per LIN 2.2 specification, including automatic baud rate detection, checksum calculation, and wake-up frame generation without firmware overhead. It uses dedicated reload timers for precise bit timing across 1–20 kbps ranges.

What is the maximum operating frequency when using the main CR PLL clock?

When configured with a main CR clock (4 MHz ±2%) and PLL multiplication rate of 4, the MB95F652EPFT-G-SNE2 achieves a stable 16 MHz ±2% main clock, yielding a maximum machine clock frequency of 16.25 MHz. This setting enables minimum instruction execution time of 61.5 ns.

Can the UART/SIO channel be used simultaneously with I²C on the same physical pins?

No. The UART/SIO channel and one I²C channel share the same pin pair (P10/P11). Function selection is controlled by register configuration at runtime, but concurrent use is not supported. The second I²C channel (P60/P61) remains independently available.

Is the Flash memory security feature reversible after activation?

No. Once the Flash security lock is enabled via the security bit in the option byte, all serial programming and on-chip debug access are permanently disabled. The only recovery method is full chip erase-which also clears security bits-but requires high-voltage programming mode unavailable in standard operation.
