Product details

Overview

CY95F634KPMC-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit Flash microcontroller based on the F2MC-8FX CPU core, featuring 20 KB flash memory, 1024 bytes RAM, and integrated LIN-UART, I²C, UART/SIO, and 8/10-bit 8-channel ADC. It operates at up to 16.25 MHz machine clock (via external clock), supports four low-power standby modes, and targets embedded control in automotive body electronics and industrial sensors.

For engineers reviewing the CY95F634KPMC-G-UNE2 datasheet, CY95F634KPMC-G-UNE2 pinout, CY95F634KPMC-G-UNE2 application, or CY95F634KPMC-G-UNE2 equivalent, key selection criteria include its LIN-UART master/slave capability, dual-bank Flash for concurrent read/program, 16-bit PPG timer with external trigger support, and built-in low-voltage detection reset (LVD) - all confirmed in Rev. *G of Document 002-04627.

Technical Context

This MCU implements a dedicated LIN-UART peripheral with full-duplex double buffer, programmable baud rate via reload timer, and configurable as LIN master or slave per ISO 9141-2/KWP2000. Its multi-pulse generator (MPG) integrates a 16-bit PPG timer, 16-bit reload timer, event counter, and waveform sequencer for closed-loop DC motor control without external logic.

The F2MC-8FX core delivers 136 basic instructions with hardware multiplication/division, 16-bit arithmetic, and bit-manipulation support. Clock supervision includes independent main/sub-oscillation monitoring, while dual-bank Flash enables real-time firmware updates with zero downtime during field upgrades.

Pinout & Package

CY95F634KPMC-G-UNE2 is housed in a 32-pin LQFP package (JEDEC MS-026, body size 7 mm × 7 mm, 0.8 mm pitch), designated LQB032 per Infineon's package mapping. Pin functions are validated per Document 002-04627 Rev. *G, Page 6 (top-view assignment).

Pin/Terminal	Circuit Role	Design Meaning
V_SS (Pins 1, 16)	Ground reference	Dual ground pins reduce noise coupling and improve ADC accuracy in mixed-signal operation
V_CC (Pin 32)	Power supply	Single 5.0 V ±10% supply input supporting full-speed operation and internal LVD monitoring
PF0/X0, PF1/X1 (Pins 2–3)	Main oscillator inputs	Accepts crystal (up to 16.25 MHz) or external clock; enables precise timing for LIN baud generation
PF2/RST (Pin 4)	Reset input	Active-low reset with internal pull-up; supports both power-on reset and external reset assertion
P00–P07 (Pins 13–15, 20–21, 24–25)	General-purpose I/O	25 CMOS I/O + 4 N-ch open-drain ports; AN00–AN07 mapped for ADC; INT00–INT07 for edge-triggered interrupts
P60–P67 (Pins 9–12, 26–29)	Peripheral multiplexed I/O	Host SDA/SCL (I²C), TO10/TO11 (timer outputs), OPT0–OPT5 (output compare), TRG1 (MPG external trigger)
P10–P17 (Pins 5–8, 17–19)	Communication & debug	PPG10/PPG11 (PWM), CMP0_O/N (comparator), DBG/EC0 (1-wire debug), UI0/UO0/UCK0/SNI0 (LIN-UART signals)

Key Features

Feature	Design Value
Dual-bank Flash memory	Enables background programming: application code executes from one bank while firmware update writes to the other - critical for fail-safe OTA updates
Multi-pulse generator (MPG)	Integrated DC motor controller with waveform sequencer, event counter, and buffered 16-bit timer - eliminates need for external motor driver logic
Configurable LIN-UART	Supports both LIN master (scheduler) and slave (node) roles with automatic sync-break detection and checksum validation per LIN spec
Low-voltage detection (LVD)	Four user-selectable threshold/release pairs allow precise brown-out response tuning for battery-powered systems (e.g., 3.5 V detect / 3.7 V release)
Hardware watchdog + software watchdog	Dual independent watchdogs - hardware WDT uses main clock for fast fault recovery; software WDT uses sub-CR clock for ultra-low-power monitoring

Applications

Automotive Body Control Module

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit LIN-capable microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SPC560B50L5	32-bit Power Architecture core, 512 KB Flash, integrated CAN/LIN, requires external 5 V regulator	Targets higher-complexity automotive ECUs with CAN+LIN coexistence; not pin-compatible	Select when CAN bus integration and ASIL-B functional safety compliance are required - not a drop-in replacement.
RL78/F13	16-bit RL78 core, 64 KB Flash, LIN master only (no slave mode), no built-in LVD	Suitable for cost-sensitive LIN slave nodes; lacks MPG and dual-bank Flash for OTA	Choose for simpler LIN slave applications where motor control or field-upgradable firmware are not needed.

Compared with SPC560B50L5 and RL78/F13, CY95F634KPMC-G-UNE2 uniquely combines LIN master/slave flexibility, on-chip LVD with four thresholds, and dual-bank Flash in an 8-bit footprint - making it optimal for compact, self-contained LIN nodes requiring robust power management and firmware agility.

FAQ

What is the maximum operating frequency of the CY95F634KPMC-G-UNE2?

The CY95F634KPMC-G-UNE2 achieves a maximum machine clock frequency of 16.25 MHz when using an external clock source. This corresponds to a minimum instruction execution time of 61.5 ns. The main oscillation clock supports up to 16.25 MHz, and the main CR PLL can generate 8/10/12/16 MHz outputs depending on the selected multiplication rate - all verified in Section 18.4 of Document 002-04627 Rev. *G.

Does this MCU support LIN 2.2 protocol natively?

Yes - the integrated LIN-UART peripheral supports full LIN 2.2 functionality including master and slave modes, automatic sync-break detection, checksum calculation (classic/enhanced), and configurable baud rates via dedicated reload timer. It complies with ISO 9141-2 and SAE J2602 standards as documented in Sections 1 and 19 of the hardware manual.

How many I/O pins support analog input for the ADC?

Eight pins - P00 through P07 - are configured as AN00 to AN07 and support 8/10-bit ADC conversion. All eight channels share a single sample-and-hold circuit and are accessible via software-controlled channel scanning. Input voltage range is V_SS to V_CC, with typical INL of ±1 LSB (10-bit mode) per Section 18.5 of the datasheet.

Is on-chip debug supported, and what interface does it use?

Yes - on-chip debug is implemented via 1-wire serial control using the DBG pin (P12). It supports asynchronous serial programming, breakpoint setting, and register inspection without halting real-time peripherals. Connection requires only V_CC, V_SS, and the DBG signal to an Infineon-compatible programmer, as detailed in Chapter 25 of the Hardware Manual.
