It operates at up to 16 MHz (62.5 ns instruction cycle), supports 8/10-bit ADC (8 channels, 6.125 µs conversion), and delivers real-time control for automotive body electronics and industrial PLC modules.
For engineers reviewing the CY90387PMT-GT-350E1 datasheet, CY90387PMT-GT-350E1 pinout, CY90387PMT-GT-350E1 application, or CY90387PMT-GT-350E1 equivalent, this page provides verified technical context, package mapping to LQFP-48, CAN timing compliance, low-power mode behavior, and validated alternative MCU options for legacy design continuity.
Technical Context
The CY90387PMT-GT-350E1 implements the F2MC-16LX architecture with 24-bit addressing, 32-bit accumulator for long-word arithmetic, and 23 addressing modes optimized for C-language compilation. Its instruction set includes enhanced multiply/divide, barrel shift, and RETI instructions supporting multitasking RTOS environments.
It integrates a full-CAN controller compliant with ISO 11898-1:2003 (Ver 2.0A/B), eight message buffers, and programmable bit timing (10 kbps–1 Mbps at 16 MHz clock). Peripheral resources include dual 16-bit reload timers, four-channel input capture, 8/16-bit PPG timer, and DTP/external interrupt with edge/level sensitivity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit CAN microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MB90F387 | Mask ROM (no Flash); identical peripheral set and pinout; lacks in-field reprogrammability | Suitable only for high-volume, fixed-function designs where firmware never changes post-manufacture | Select when cost sensitivity outweighs field update capability and ROM content is finalized |
| MB90387S | 36 GPIO (vs. 34); same Flash/RAM; identical CAN/ADC/timer specs; LQFP-48 pin-compatible | Provides two additional general-purpose I/Os for expanded sensor/actuator connectivity without PCB redesign | Choose when extra I/O is needed and board layout allows same footprint; no firmware changes required |

FAQ
Does CY90387PMT-GT-350E1 support CAN FD?
No. The integrated CAN controller complies strictly with ISO 11898-1:2003 (CAN 2.0A/B) and does not implement CAN FD features such as flexible data-rate or extended data length. Bit rates are limited to 1 Mbps maximum at 16 MHz clock, with standard 11-bit or 29-bit identifiers only.
What is the minimum supply voltage for reliable ADC operation?
AVcc must be maintained at ≥3.5 V for guaranteed 10-bit ADC linearity and monotonicity. At 3.5 V, the 10-bit full-scale range is 0–3.5 V with ±1 LSB INL; operation below 3.5 V may cause missing codes or increased DNL beyond specification limits.
Can the 32-bit accumulator be used for floating-point math?
No. The 32-bit accumulator supports only integer arithmetic (addition, subtraction, multiplication, division) and bit manipulation. It lacks IEEE-754 format support, exponent handling, or hardware floating-point instructions; software libraries are required for FP operations.
Is external crystal required for CAN timing accuracy?
Yes. CAN bit timing stability requires an external crystal (typically 4 MHz or 8 MHz) feeding the on-chip PLL. The internal RC oscillator lacks sufficient ppm stability for CAN bus synchronization; using it risks bit errors and bus off conditions under temperature variation.
