Infineon Technologies CY96F6B6RBPMC-GS-UJE1

Overview

CY96F6B6RBPMC-GS-UJE1 from Infineon Technologies (formerly Cypress) is a 16-bit F2MC-16FX microcontroller with CAN 2.0A/B support, 32 MHz max CPU frequency via on-chip PLL, 512 KB flash, 64 KB RAM, and integrated LCD controller (4COM × 36SEG). It operates from 2.7–5.5 V, supports 13 low-power modes, and targets automotive body control modules requiring ISO16845-certified CAN communication.

For engineers reviewing the CY96F6B6RBPMC-GS-UJE1 datasheet, CY96F6B6RBPMC-GS-UJE1 pinout, CY96F6B6RBPMC-GS-UJE1 application, or CY96F6B6RBPMC-GS-UJE1 equivalent, key selection criteria include CAN bit rate up to 1 Mbps, dual-bank flash for safe firmware updates, sub-31.2 ns instruction cycle time, and hardware watchdog with window function.

Technical Context

The CY96F6B6RBPMC-GS-UJE1 implements the F2MC-16FX RISC-like architecture with 8-byte instruction queue, signed 16×16 multiply and 32/16 divide instructions, and 23 addressing modes optimized for real-time embedded control. Its clock tree decouples CPU (up to 32 MHz) and peripheral domains using main, sub (32.768 kHz), and RC (100 kHz/2 MHz) sources.

It integrates ISO16845-certified CAN controller with 32 message objects, programmable FIFO mode, loop-back self-test, and disabled automatic retransmission for time-triggered operation. The A/D converter is SAR-type with 10-bit resolution, range comparator, and trigger sources including PPG and reload timers.

FAQ

What is the maximum operating temperature range for CY96F6B6RBPMC-GS-UJE1?

The CY96F6B6RBPMC-GS-UJE1 is rated for −40 °C to +105 °C ambient temperature per its qualified automotive grade (AEC-Q100 Grade 2). This range is validated across all electrical characteristics including CAN timing, flash programming, and ADC linearity, with thermal derating applied above 85 °C for sustained operation.

Does this MCU support CAN FD or only classical CAN?

CY96F6B6RBPMC-GS-UJE1 supports only Classical CAN (ISO 11898-1:2003) compliant with CAN 2.0A and 2.0B protocols, up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. Its CAN controller is ISO16845-certified for classical frame formats only.

How is flash security implemented on this device?

Flash security uses a dedicated Flash Security Register (FSR) that disables external read-out via serial programming interface when set. Once enabled, the register cannot be cleared without bulk erase - which also erases all user code. Security is enforced at boot time by Boot ROM, and low-voltage detection prevents unauthorized write/erase during brown-out conditions.

Can the LCD controller drive static or multiplexed displays?

The LCD controller supports only multiplexed (static drive is not supported). It delivers 4 common (COM) outputs and up to 36 segment (SEG) outputs, enabling 4×36 dot-matrix or alphanumeric segment configurations. Duty cycle is fixed at 1/3 bias, and frame frequency is programmable from 32 Hz to 128 Hz using internal clock dividers.
