Infineon Technologies CY95F694KPMC-G-UNE2

Overview

CY95F694KPMC-G-UNE2 from Infineon Technologies (formerly Cypress) is an 8-bit F2MC-8FX microcontroller with 20 KB Flash, 512 B RAM, and integrated LIN-UART, dual 8/16-bit composite timers, and 8-channel 8/10-bit ADC. It operates at up to 16.25 MHz machine clock (via external clock), supports four low-power standby modes, and targets automotive body control modules requiring LIN communication and motor timing.

For engineers reviewing the CY95F694KPMC-G-UNE2 datasheet, CY95F694KPMC-G-UNE2 pinout, CY95F694KPMC-G-UNE2 application, or CY95F694KPMC-G-UNE2 equivalent, key selection criteria include LIN master/slave capability, 8-channel ADC resolution selectability (8/10-bit), Flash security lock, dual-bank simultaneous read/erase operation, and sub-CR PLL clock options (8–16 MHz ±2%).

Technical Context

The device 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. It integrates a multi-pulse generator (MPG) for DC motor control, featuring a dedicated waveform sequencer with buffered 16-bit timer and compare-clear function.

Its clock system supports selectable main sources (external up to 32.5 MHz, main CR PLL at 8/10/12/16 MHz ±2%) and subclocks (32.768 kHz or 100 kHz sub-CR). The LIN-UART channel provides full-duplex double-buffered asynchronous transfer with programmable baud rate generation and LIN master/slave mode support.

FAQ

Does CY95F694KPMC-G-UNE2 include a LIN physical layer (LIN PHY)?

No. CY95F694KPMC-G-UNE2 integrates a LIN protocol controller (LIN-UART) but requires an external LIN transceiver (e.g., TLE7259-3GE) for bus-level signal conditioning and fault protection. The LIN-UART handles frame formatting, checksum, and wake-up detection in hardware.

What is the maximum operating temperature range for this part?

The CY95F694KPMC-G-UNE2 is rated for −40°C to +105°C ambient temperature, meeting automotive under-hood and interior module requirements. This rating is validated per JEDEC JESD22-A108 and confirmed in the "Recommended Operating Conditions" section of datasheet 002-04692 Rev. *E.

Can the Flash memory be reprogrammed in-system without removing the chip?

Yes. The device supports in-system programming (ISP) via its single-wire on-chip debug interface. No external programmer is needed - firmware updates can be performed through UART or custom bootloader using the embedded algorithm with erase-suspend/resume commands.

Is the 8/10-bit ADC differential-input capable?

No. The 8-channel ADC accepts only single-ended inputs referenced to AVSS. Each channel can be configured for either 8-bit (256 steps) or 10-bit (1024 steps) resolution, but differential pair sampling (e.g., AD0–AD1 as differential pair) is not supported per the "A/D Converter" section (page 109) of the datasheet.
