Product details
Overview
MB95F282KPF-G-SNE1 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 8 KB Flash, 240 bytes RAM, 13 I/O ports (11 CMOS + 2 N-ch open-drain), LIN-UART interface, and 5-channel 8/10-bit A/D converter. It operates at up to 16.25 MHz machine clock using external or CR oscillator sources and targets automotive body control modules, industrial sensor nodes, and smart appliance sub-systems requiring LIN communication and low-power operation.
For engineers reviewing the MB95F282KPF-G-SNE1 datasheet, MB95F282KPF-G-SNE1 pinout, MB95F282KPF-G-SNE1 application, or MB95F282KPF-G-SNE1 equivalent, key selection criteria include LIN master/slave capability, dual-bank Flash security, 1-wire on-chip debug, sub-CR clock-based watchdog timing, and standby mode support (stop/sleep/watch/time-base timer).
Technical Context
The MB95F282KPF-G-SNE1 implements the F2MC-8FX CPU core with 136 instructions, 8-/16-bit arithmetic, bit manipulation, and multiplication/division support. Its clock system supports main OSC (up to 16.25 MHz), external clock (32.5 MHz), and main CR (1/8/10 MHz ±3%) with selectable sub-clock sources including 32.768 kHz sub-OSC and 50–200 kHz sub-CR.
It integrates a full-duplex LIN-UART with double-buffering, clock-synchronized/asynchronous serial transfer, and LIN master/slave functionality. The 8/16-bit composite timer includes PWM, PWC, input capture, and square-wave output, while the 8/10-bit A/D converter offers selectable resolution across 5 channels with programmable input voltage levels (CMOS/hysteresis).

FAQ
Is MB95F282KPF-G-SNE1 pin-compatible with MB95F282H variants?
Yes - MB95F282KPF-G-SNE1 shares identical 32-pin QFP (FPT-32P-M19) mechanical dimensions and pin mapping with MB95F282H, differing only in Flash memory type (K = Flash with security, H = mask ROM). All I/O, power, clock, and debug pins align exactly, enabling drop-in replacement where firmware security is required.
What LIN protocol versions does the on-chip LIN-UART support?
The MB95F282KPF-G-SNE1 LIN-UART supports LIN 2.0, LIN 2.1, and LIN 2.2 specifications. It implements full master and slave functionality, including automatic baud rate detection, checksum calculation (classic/enhanced), and frame scheduling via reload timer - verified in Cypress Application Note AN94672.
Does the device support in-system programming via the 1-wire debug interface?
Yes - the 1-wire serial debug interface supports full in-system programming (ISP) of Flash memory, including erase, program, and verify operations, using Cypress's CY8CKIT-014 programmer and associated PSoC Programmer software v3.27+. No external HV programming voltage is required.
How is the low-voltage detection reset configured on this part?
MB95F282KPF-G-SNE1 does not integrate a low-voltage detection (LVD) reset circuit - this feature is present only on MB95F283H/K and MB95F284H/K variants. The MB95F282K relies on power-on reset (POR) and external supervision for brown-out protection, as confirmed in Rev. *B datasheet Section 1.2 and Table 1.
