Infineon Technologies CY96F385RSBPMC-GS167UJE2

Overview

CY96F385RSBPMC-GS167UJE2 from Cypress Semiconductor is a 16-bit F2MC-16FX microcontroller with 288 KB Flash, 16 KB RAM, and integrated CAN 2.0A/B controller, 16-channel 10-bit ADC, LCD controller (4 COM × 65 SEG), and programmable pulse generator. It operates at up to 56 MHz via internal PLL (17.8 ns instruction cycle), supports dual clock domains, and targets automotive body control and industrial HMI applications.

For engineers reviewing the CY96F385RSBPMC-GS167UJE2 datasheet, CY96F385RSBPMC-GS167UJE2 pinout, CY96F385RSBPMC-GS167UJE2 application, or CY96F385RSBPMC-GS167UJE2 equivalent, key selection criteria include CAN interface count (1 channel), Flash sector protection, low-voltage reset persistence (suffix "S"), LQFP-120 package compatibility, and dual-clock domain configuration for real-time peripheral timing independence.

Technical Context

The CY96F385RSBPMC-GS167UJE2 implements the F2MC-16FX CPU core with 23 addressing modes, barrel shift, and signed multiply/divide instructions - enabling deterministic control-loop execution in motor and sensor systems. Its clock tree separates CPU (up to 56 MHz) and peripheral domains, with independent selection among main oscillator (3–16 MHz), subclock (32–100 kHz), or RC oscillator (100 kHz/2 MHz).

It integrates one ISO16845-certified CAN 2.0A/B controller (1 Mbit/s, 32 message objects), a 16-channel SAR ADC with external trigger support, and a dedicated LCD controller supporting 4×65 segment drive with programmable bias and frame period. The device uses a 0.18 μm CMOS process and includes an on-chip voltage regulator for EMI reduction and low-power operation across 13 operating modes.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The CY96F385RSBPMC-GS167UJE2 achieves a maximum CPU frequency of 56 MHz using its internal PLL with a 4 MHz external resonator. This yields a minimum instruction cycle time of 17.8 ns. The PLL multiplier is configurable from ×1 to ×25, and the device maintains full functionality across all supported frequencies within recommended operating conditions (VCC = 4.5–5.5 V, TA = –40°C to +85°C).

Does this MCU support CAN FD or only classical CAN 2.0?

This MCU supports only classical CAN 2.0 Part A and B, with bit rates up to 1 Mbit/s. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. The CAN controller is ISO16845 certified for conformance testing but lacks the protocol extensions required for CAN FD operation.

How many I/O pins can be used as general-purpose GPIOs?

The CY96F385RSBPMC-GS167UJE2 provides 96 general-purpose I/O pins (as indicated by suffix "S" in product lineup). All external pins except dedicated power, reset, and oscillator terminals are configurable as GPIOs - including COM/SEG, CAN, USART, and ADC pins - with bit-wise programmable direction, pull-up, drive strength, and input level (CMOS-Schmitt/TTL).

Is the Flash memory capable of in-system programming (ISP)?

Yes, the 288 KB Flash supports in-system programming via the Serial Programming Communication Interface (SPCI) using standard UART signals (TX/RX). It implements embedded erase/write algorithms with completion flags, sector-level protection, and low-voltage detection during erase - enabling field firmware updates without removing the device from the target board.
