Infineon Technologies CY95F818KPMC-G-UNE2

Overview

CY95F818KPMC-G-UNE2 from Cypress Semiconductor is an 8-bit F2MC-8FX microcontroller with 60 KB Flash, 2 KB RAM, 58 I/O ports (54 CMOS + 4 N-ch open-drain), and dual-bank Flash enabling concurrent read/program operations. It integrates 12-channel 8/10-bit ADC, two 16-bit PPG timers, LIN-UART, I²C, UART/SIO, and four low-power standby modes. Used in industrial control panels requiring real-time sensor interfacing and deterministic communication.

For engineers reviewing the CY95F818KPMC-G-UNE2 datasheet, CY95F818KPMC-G-UNE2 pinout, CY95F818KPMC-G-UNE2 application, or CY95F818KPMC-G-UNE2 equivalent, key selection criteria include its 16.25 MHz max machine clock, software-controllable LVD reset, on-chip debug via 1-wire serial, dual-operation Flash architecture, and LIN master/slave capability for automotive body electronics.

Technical Context

The device implements the F2MC-8FX CPU core with 136 basic instructions, 1–3 byte instruction length, and support for 16-bit arithmetic, multiplication/division, and bit manipulation. Its memory map includes dedicated I/O area (0x0000–0x007F), extended I/O (0x0F80–0x0FFF), and program/data spaces with banked Flash access.

Peripherals are tightly coupled to the CPU via dedicated interrupt vectors and register-mapped I/O. The clock system supports multiple sources: main oscillation (up to 16.25 MHz machine clock), external clock (32.5 MHz input → 16.25 MHz machine), CR-based PLL (8/10/12/16 MHz ±2%), and subclock options including 32.768 kHz crystal or 100 kHz CR oscillator.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability microcontrollers and programmable systems-on-chip for industrial, automotive, and consumer applications.

The MB95810K Series targets cost-sensitive, real-time embedded systems requiring mixed-signal integration, low-power operation, and field-proven Flash reliability - especially where legacy 8-bit codebases must be maintained with minimal hardware changes.

FAQ

What is the maximum operating frequency of the CY95F818KPMC-G-UNE2?

The maximum machine clock frequency is 16.25 MHz, achieved when using an external clock source up to 32.5 MHz with 2× division. At this rate, the minimum instruction execution time is 61.5 ns. The main oscillator supports up to 16.25 MHz machine clock (32.5 MHz crystal input), and the CR-based PLL delivers 8/10/12/16 MHz ±2% outputs depending on multiplication factor.

Does the CY95F818KPMC-G-UNE2 support in-system programming?

Yes - it supports serial programming via the on-chip 1-wire debug interface (P12 pin), enabling flash erase, program, and verification without removing the device from the PCB. Programming uses asynchronous serial mode with baud rate generated internally; no external programmer hardware is required beyond a simple level-shifter circuit.

How many analog input channels does the integrated ADC support?

The device has 12 dedicated analog input pins (P30–P37, P40–P43) supporting both 8-bit and 10-bit conversion resolution. Each channel can be triggered by software, timer overflow, or the external ADTG signal. Input range is AVSS to AVCC, and the ADC includes built-in sample-and-hold with programmable acquisition time.

Is the LIN-UART peripheral compliant with LIN 2.x specifications?

Yes - the hardware LIN-UART supports LIN 2.1 physical layer timing, automatic checksum generation (classic and enhanced), response error detection, and both master and slave roles. It operates independently of the CPU for frame transmission/reception, and supports configurable baud rates from 1.2 to 20 kbps using the dedicated reload timer.
