Infineon Technologies CY90F387SPMT-GTE1

Overview

CY90F387SPMT-GTE1 from Cypress Semiconductor is a 16-bit F2MC-16LX microcontroller with integrated 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-based clock multiplication (4–16 MHz), and delivers 62.5 ns minimum instruction execution time at 16 MHz - deployed in automotive body control modules requiring real-time CAN communication and analog sensing.

For engineers reviewing the CY90F387SPMT-GTE1 datasheet, CY90F387SPMT-GTE1 pinout, CY90F387SPMT-GTE1 application, or CY90F387SPMT-GTE1 equivalent, key selection criteria include its on-chip CAN controller with 8 message buffers, 8-channel 8/10-bit A/D converter (6.125 µs conversion time), dual 16-bit reload timers, and low-power sleep/watch/stop modes for battery-sensitive embedded systems.

Technical Context

The CY90F387SPMT-GTE1 implements the F2MC-16LX CPU core with 24-bit addressing, 32-bit accumulator for long-word arithmetic, and 351 instructions supporting bit/byte/word/long-word data types. Its interrupt architecture features 8 priority levels and 34 sources, including CAN wakeup, DTP, and ICU-triggered interrupts.

Peripheral integration includes a full-duplex UART (SCI) with double-buffering, 8/16-bit PPG timer (configurable as four 8-bit or two 16-bit channels), 16-bit input-capture timer (4 channels), and time-base/watchdog/watch timers driven by either main oscillator (4 MHz) or sub-clock (8.192 kHz).

FAQ

Does CY90F387SPMT-GTE1 require an external CAN transceiver?

Yes - the device integrates only the CAN protocol controller (MAC layer); an external physical-layer transceiver (e.g., TJA1042, SN65HVD230) is required for bus connection. The controller supports standard CAN 2.0A/B signaling and provides eight message buffers with programmable acceptance filtering.

What is the maximum operating frequency of the internal PLL?

The internal PLL multiplies the external crystal or ceramic resonator frequency by factors of 1× to 4×. With a 4 MHz oscillator, the PLL delivers machine clocks of 4 MHz, 8 MHz, 12 MHz, or 16 MHz - enabling a minimum instruction execution time of 62.5 ns at 16 MHz.

Can the 8/10-bit A/D converter perform simultaneous sampling across all 8 channels?

No - the A/D converter performs sequential conversions. In sequential mode, it scans up to 8 selected channels in order, with each conversion taking 6.125 µs at 16 MHz. Simultaneous sampling requires external analog multiplexing or a dedicated multi-channel simultaneous-sampling ADC.

Is the CY90F387SPMT-GTE1 pin-compatible with other MB90385-series devices like MB90F387S?

No - CY90F387SPMT-GTE1 (LQFP-48) maps to MB90F387, while MB90F387S uses the same LQFP-48 package but adds two additional I/O ports (36 vs 34). Pin functions are identical where shared, but P35/P36 serve as X0A/X1A in MB90F387S and are unused in CY90F387SPMT-GTE1 per the pin assignment diagram.
