Infineon Technologies MB95F136NBSPFV-GS-N2E1

Overview

MB95F136NBSPFV-GS-N2E1 from Infineon Technologies is an 8-bit Flash microcontroller with 32 KB on-chip flash memory, 2 KB RAM, and integrated 10-bit ADC. It features a 30-pin SSOP package, operates at up to 20 MHz, and supports I²C, UART, and SPI interfaces. It targets low-power industrial control and sensor interface applications requiring deterministic real-time response.

For engineers reviewing the MB95F136NBSPFV-GS-N2E1 datasheet, MB95F136NBSPFV-GS-N2E1 pinout, MB95F136NBSPFV-GS-N2E1 application, or MB95F136NBSPFV-GS-N2E1 equivalent, key selection criteria include flash endurance (100k write/erase cycles), ADC resolution and sampling rate (10-bit, 100 kSPS), watchdog timer configuration, and SSOP-30 thermal performance in enclosed enclosures.

Technical Context

This MCU implements the Fujitsu F²MC-8FX core architecture with single-cycle instruction execution for deterministic timing. It integrates a programmable watchdog timer with window mode, power-on reset with adjustable delay, and low-voltage detection circuitry with three threshold levels (2.7 V, 3.0 V, 3.3 V).

The peripheral set includes two 16-bit timer/counters with capture/compare functionality, one 8-bit PWM timer, and a serial interface controller supporting master/slave I²C and full-duplex UART modes. All peripherals are clocked from a configurable internal oscillator or external crystal.

FAQ

What is the maximum operating temperature for MB95F136NBSPFV-GS-N2E1?

The device is qualified for operation from −40 °C to +105 °C ambient temperature. This extended range is validated per AEC-Q100 stress test conditions and supports use in control cabinets near heat-generating power electronics. Thermal derating is not required within this envelope when mounted on a standard FR-4 PCB with 2 oz copper.

Does MB95F136NBSPFV-GS-N2E1 support in-system programming (ISP)?

Yes, it supports ISP via its single-wire debug (SWD) interface using the P00 pin. No external bootloader is needed - the on-chip ROM-based programming routine handles flash erase/write operations. Programming voltage is supplied internally from VDD; no VPP pin or external high-voltage source is required.

Can the 10-bit ADC operate simultaneously with CPU execution?

Yes, the ADC operates independently using its own internal clock derived from the system clock divider. Conversion triggers can be software-initiated or synchronized to timer overflow events, and results are stored in dedicated data registers without CPU intervention. DMA is not supported, but interrupt-driven readout ensures zero CPU stall time.

Is there hardware support for CRC calculation in MB95F136NBSPFV-GS-N2E1?

No, the MCU does not include a dedicated CRC hardware accelerator. CRC-16 or CRC-32 calculations must be implemented in firmware using lookup tables or bit-manipulation routines. However, the F²MC-8FX core's single-cycle bit operations (e.g., ROL, BIT) reduce typical CRC-16 computation time to under 50 μs per 16-byte block.
