Infineon Technologies MB95F212KPF-G-SNE2

Overview

MB95F212KPF-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller in the MB95210H series, designed for compact embedded control applications requiring low pin count and integrated analog peripherals. It features 4 KB Flash memory, 240 B RAM, 4 I/O ports (3 CMOS + 1 N-ch open-drain), 2-channel 8/10-bit A/D converter, and a single 8/16-bit composite timer - all operating at up to 10 MHz machine clock using internal CR oscillator. It targets cost-sensitive industrial sensors and appliance sub-systems.

For engineers reviewing the MB95F212KPF-G-SNE2 datasheet, MB95F212KPF-G-SNE2 pinout, MB95F212KPF-G-SNE2 application, or MB95F212KPF-G-SNE2 equivalent, key selection factors include its 8-pin SOP package, dedicated RSTX/PF2 reset input, LIN-UART omission (vs. F20x variants), sub-100 µA standby current in watch mode, and flash security lock capability for firmware protection.

Technical Context

The MB95F212KPF-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 including multiplication and division. Its clock system includes selectable main internal CR oscillator (1/8/10 MHz ±3%) and sub-CR oscillator (50–200 kHz), but excludes main/sub-OSC crystal inputs - confirming its role as a low-cost, crystal-free control MCU.

It integrates a hardware watchdog timer with configurable timeout (min 105 ms at 10 MHz), low-voltage detection reset circuit, clock supervisor counter, and on-chip debug via 1-wire serial interface. The absence of LIN-UART and reduced I/O count (vs. F20x series) reflects its specialization for minimal-footprint timing and sensor readout tasks rather than communication-intensive nodes.

Key Specifications

Pinout & Package

MB95F212KPF-G-SNE2 is housed in an 8-pin plastic SOP (Small Outline Package) with 1.27 mm pitch, footprint compatible with JEDEC MS-012AC. Pin 1 is marked by notch or dot; device orientation follows standard SOP top-view labeling.

FAQ

Does MB95F212KPF-G-SNE2 support external crystal oscillation?

No. Unlike MB95F20xH/K variants, the MB95F212KPF-G-SNE2 omits X0/X1 and X0A/X1A pins entirely. Its clock system relies solely on internal CR oscillators (1/8/10 MHz main, 50–200 kHz sub), confirmed by pin assignment tables and electrical characteristics section of Document 002-07463 Rev. *B.

Can the on-chip debug interface be used after flash security is enabled?

No. Enabling flash security lock disables all access to Flash memory and debug registers via the 1-wire interface. The security bit is irreversible - once set, firmware updates require full chip erase via dedicated programming voltage (Vpp = +10 V) applied to RSTX/PF2, as specified in the Flash Memory Programming section.

What is the maximum sink current capability of the N-ch open-drain port (P02)?

The N-ch open-drain output on P02 supports up to 20 mA sink current at VCC = 5.5 V and TA = 25°C, per DC Characteristics Table on page 31 of Document 002-07463 Rev. *B. It is rated for continuous operation at ≤10 mA to ensure thermal stability in sealed enclosures.

Is LIN-UART functionality available on MB95F212KPF-G-SNE2?

No. LIN-UART is explicitly excluded from the MB95F212K/F213K/F214K product group, as stated in the "Differences Among Products" table (page 3). Pin functions SIN/SOT/SCK are absent from the 8-pin SOP pinout, and no LIN-related registers appear in the I/O map for this variant.
