FAQ

What is the maximum operating frequency of the LPC55S04JBD64E?

The LPC55S04JBD64E operates at a maximum CPU frequency of 96 MHz. This is achieved using the internal 96 MHz Free Running Oscillator (FRO) or PLL-derived clocks. The FRO is trimmed to ±1% accuracy across 0 °C to 85 °C and ±2% across −40 °C to 105 °C, ensuring reliable timing in industrial environments. All peripherals, including the 16-bit ADC and Flexcomm interfaces, are fully functional at this rate.

Does the LPC55S04JBD64E support secure boot with public-key verification?

Yes, the LPC55S04JBD64E supports secure boot using RSASSA-PKCS1-v1_5 signatures of SHA256 digests. It validates images with RSA-2048 or RSA-4096 public keys stored in x.509 certificates, supports up to four revocable Root of Trust keys in protected flash, and enforces anti-rollback via image key certificate serial number revocation - all implemented in ROM bootloader without software dependency.

How many ADC channels does the LPC55S04JBD64E provide, and what is their resolution?

The LPC55S04JBD64E integrates a 16-bit successive approximation ADC capable of up to 2.0 million samples per second. It supports nine differential input channel pairs (or 18 single-ended inputs), with simultaneous sampling on paired channels. The ADC includes an integrated temperature sensor and supports multiple trigger sources including timers and external events, making it suitable for high-fidelity sensor acquisition in motor control or environmental monitoring.

What package type is used for the LPC55S04JBD64E, and what are its mechanical dimensions?

The LPC55S04JBD64E uses the HTQFP64 package (SOT 855-5): a plastic low-profile quad flat package with 64 leads, 10 mm × 10 mm body size, and 0.5 mm lead pitch. It includes an exposed thermal pad that must be connected to VSS for thermal management. This package is compatible with standard surface-mount assembly processes and supports industrial temperature range operation (−40 °C to +105 °C).

Can the LPC55S04JBD64E execute cryptographic operations without software overhead?

Yes, the LPC55S04JBD64E offloads cryptographic operations via dedicated hardware: PRINCE performs real-time AES-128 flash encryption/decryption; CASPER accelerates ECC scalar multiplication; PUF generates device-unique keys from SRAM fingerprinting; and HASH-AES provides DMA-accelerated SHA2 and AES operations. These blocks operate independently of the Cortex-M33 core, enabling concurrent application execution and cryptographic processing with deterministic latency.
