Infineon Technologies CY90F387SPMCR-GE1

Overview

CY90F387SPMCR-GE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated full-CAN 2.0A/B controller, 64 KB Flash ROM, 2 KB RAM, and 34 general-purpose I/O ports including four high-current outputs. It operates from 3.5 V to 5.5 V, supports PLL-multiplied clock up to 16 MHz (62.5 ns min instruction time), and features an 8/10-bit 8-channel ADC with 6.125 µs conversion time - deployed in automotive body control modules requiring real-time CAN communication and analog sensor interfacing.

For engineers reviewing the CY90F387SPMCR-GE1 datasheet, CY90F387SPMCR-GE1 pinout, CY90F387SPMCR-GE1 application, or CY90F387SPMCR-GE1 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities (CAN, UART, PPG timers, EI2OS), and precise alternative part guidance for industrial and automotive embedded design.

Technical Context

The CY90F387SPMCR-GE1 implements the F2MC-16LX architecture with 24-bit internal addressing, 32-bit accumulator for long-word arithmetic, and 23 addressing modes optimized for C-language compilation and multitasking. Its instruction set includes enhanced multiply/divide, barrel shift, and RETI instructions - enabling deterministic real-time control loops.

Peripheral integration includes one CAN controller (8 message buffers, 10 kbps–1 Mbps), one UART (SCI) with full-duplex double buffer, four 16-bit input-capture channels (ICU), two 16-bit reload timers, and an expanded intelligent I/O service (EI2OS) supporting up to 16 autonomous I/O channels - all synchronized to a shared 16 MHz machine clock derived from PLL multiplication of an external 4 MHz crystal.

FAQ

Does CY90F387SPMCR-GE1 support CAN FD?

No. The integrated CAN controller complies exclusively with ISO 11898-1:2015 (CAN 2.0A/B) and does not implement CAN FD frame format, bit-rate switching, or extended data length. It supports up to 8 message buffers and data rates from 10 kbps to 1 Mbps using standard 11-bit or 29-bit identifiers.

What is the maximum operating frequency of the internal PLL?

The internal PLL multiplies the external crystal frequency (e.g., 4 MHz) by factors of 1× to 4×, yielding a maximum machine clock of 16 MHz. At this frequency, the minimum instruction execution time is 62.5 ns, and the 8/10-bit ADC achieves 6.125 µs conversion time including sampling.

Can the 8/10-bit ADC operate independently of CPU intervention?

Yes. The ADC supports external trigger activation via P37/ADTG pin, and sequential conversion across up to 8 channels can be configured autonomously. Combined with EI2OS, this enables periodic sensor sampling and result storage without CPU wake-up - reducing average system power in sleep mode.

Is the LQFP-48 package RoHS-compliant and lead-free?

Yes. CY90F387SPMCR-GE1 uses a lead-free, halogen-free LQFP-48 package conforming to JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and RoHS Directive 2011/65/EU - qualified for standard Pb-free reflow profiles with peak temperature up to 260 °C.
