Infineon Technologies CY96F348HSCPQC-GSE2

Overview

CY96F348HSCPQC-GSE2 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with dual CAN interfaces, 576 KB on-chip Flash (544 KB Flash A + 32 KB Flash B), 24 KB RAM, and 100-pin LQFP package. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports 24-channel 10-bit SAR ADC, dual I²C, seven USARTs (including LIN), and real-time clock with calibration. Used in automotive body control modules requiring deterministic CAN communication and mixed-signal processing.

For engineers reviewing the CY96F348HSCPQC-GSE2 datasheet, CY96F348HSCPQC-GSE2 pinout, CY96F348HSCPQC-GSE2 application, or CY96F348HSCPQC-GSE2 equivalent, key selection criteria include dual-CAN channel count, Flash memory partitioning (A/B), 24-channel ADC resolution and trigger sources, programmable pulse generator count (16 channels), and dual-clock domain support for independent CPU/peripheral timing.

Technical Context

The CY96F348HSCPQC-GSE2 implements the F2MC-16FX CPU core with RISC-like pipelined execution, 23 addressing modes, and native 16×16 signed multiply/32÷16 divide instructions. Its clock system integrates a programmable PLL (×1–×25), dual oscillators (main 3–16 MHz crystal + sub 32–100 kHz quartz), and on-chip RC oscillator for fail-safe startup.

Peripheral architecture features two independent CAN 2.0A/B controllers (ISO16845 certified, up to 1 Mbit/s), seven full-duplex USARTs with LIN master/slave capability, and a flexible DMA controller with 6 channels assigned across ADC, CAN, USART, and I²C. The 24-channel ADC supports software/external/reload-timer triggering and dual reference voltage switching (AVRH/AVRL or AVRH2).

FAQ

What is the maximum operating frequency and corresponding instruction cycle time of the CY96F348HSCPQC-GSE2?

The CY96F348HSCPQC-GSE2 achieves a maximum CPU clock frequency of 56 MHz using its internal PLL multiplier. This yields a minimum instruction cycle time of 17.8 ns, confirmed in the datasheet's AC characteristics table (page 68). The core maintains this performance across the full industrial temperature range (−40°C to +85°C) under specified VCC conditions.

Does the CY96F348HSCPQC-GSE2 support LIN communication, and if so, how many channels?

Yes, the CY96F348HSCPQC-GSE2 supports LIN communication via seven full-duplex USART channels (TX0–TX6 / RX0–RX6), each configurable as LIN master or slave per the SCI/LIN mode register settings. LIN functionality is implemented in hardware with automatic header detection, checksum generation, and sync field handling - no CPU overhead required for basic frame transmission.

How is Flash memory organized, and what is the endurance specification?

CY96F348HSCPQC-GSE2 contains 576 KB of on-chip Flash memory divided into 544 KB Flash A and 32 KB Flash B. Each sector supports 10,000 erase/write cycles, with guaranteed data retention of 20 years at +85°C. Sector protection and Flash security features prevent unauthorized read-out or modification of critical firmware sections.

What are the supported clock sources for the real-time clock (RTC) module?

The RTC module can be clocked from three independent sources: the 32–100 kHz sub-oscillator (quartz), the main oscillator (via programmable divider), or the on-chip 100 kHz/2 MHz RC oscillator. Clock calibration logic compensates for quartz drift, and registers for seconds, minutes, hours, and days are directly readable/writable via memory-mapped I/O at address 0xFFE000–0xFFE00F.
