Infineon Technologies MB95F212KPH-G-SNE2

Overview

MB95F212KPH-G-SNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller in the MB95210H series, packaged in 8-pin SOP. It features 4 KB flash memory, 240 B RAM, 4 I/O ports (3 CMOS + 1 N-ch open-drain), 2-channel external interrupt, and 2-channel 8/10-bit A/D converter. Designed for space-constrained embedded control in low-pin-count applications such as appliance sub-systems and sensor interface modules.

For engineers reviewing the MB95F212KPH-G-SNE2 datasheet, MB95F212KPH-G-SNE2 pinout, MB95F212KPH-G-SNE2 application, or MB95F212KPH-G-SNE2 equivalent, key selection criteria include its 8-pin SOP footprint, 4 KB flash with security lock, sub-100 µA standby current in watch mode, and LIN-UART omission-making it suitable for cost-sensitive, non-communication-intensive control tasks.

Technical Context

The MB95F212KPH-G-SNE2 implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and 61.5 ns minimum execution time at 16.25 MHz machine clock. It supports three clock sources: main internal CR (1/8/10 MHz ±3%), external clock (up to 32.5 MHz), and sub-internal CR (50–200 kHz).

It integrates a 2-channel 8/16-bit composite timer with PWM/PWC/input capture capability, hardware watchdog timer with sub-CR clock option, on-chip debug via 1-wire serial control, and flash security protection. No LIN-UART peripheral is included-distinguishing it from MB95F20xH/K variants.

FAQ

Does MB95F212KPH-G-SNE2 support LIN communication?

No. Unlike MB95F20xH/K variants, the MB95F212KPH-G-SNE2 omits the LIN-UART peripheral entirely. Its pinout and functional block diagram confirm absence of SIN/SOT/HCLK pins required for LIN protocol handling. Applications requiring LIN must select MB95F202H/F202K or higher-series parts.

What is the maximum operating frequency of the MB95F212KPH-G-SNE2?

The maximum machine clock frequency is 16.25 MHz, achievable only when using an external clock source up to 32.5 MHz. With internal CR clocks, max frequencies are 10 MHz (10 MHz CR), 8.125 MHz (main OSC at 16.25 MHz), or lower depending on selected sub-clock configuration.

Can the RSTX pin be used as a general-purpose I/O after reset?

Yes. After power-on reset completes and the internal reset signal deasserts, PF2 (RSTX) becomes a fully functional CMOS general-purpose I/O port. However, it cannot serve as an input during reset assertion, and external pull-up is mandatory for reliable reset behavior.

Is external Vpp required to program the flash memory?

Yes. Flash programming and erasure require +10 V applied to the Vpp pin (not present on this 8-pin SOP package). Programming must be performed using Cypress's dedicated programmer tools that generate internal Vpp via charge pump-no external 10 V supply is needed on the target board.
