FAQ

What is the maximum operating frequency of the LPC2119FBD64,151?

The LPC2119FBD64,151 achieves a maximum CPU clock frequency of 60 MHz using its on-chip Phase-Locked Loop (PLL), which settles in 100 µs. This frequency is sustained by the 128-bit wide memory interface and accelerator architecture, enabling full-speed 32-bit instruction execution without wait states - essential for time-critical CAN message processing and PWM generation in the LPC2119FBD64,151.

Does the LPC2119FBD64,151 support dual CAN interfaces?

Yes, the LPC2119FBD64,151 integrates two independent CAN 2.0B controllers supporting data rates up to 1 Mbit/s each, with advanced acceptance filters for message filtering. This dual-CAN capability is confirmed in Table 2 of the datasheet and distinguishes it from the single-CAN LPC2109FBD64,151 - making the LPC2119FBD64,151 suitable for gateway or redundancy applications requiring simultaneous bus access.

What are the power supply requirements for the LPC2119FBD64,151?

The LPC2119FBD64,151 requires two separate power domains: a 1.8 V ±0.15 V supply (VDD(1V8) and VDDA(1V8)) for the core and analog circuitry, and a 3.3 V ±10% supply (VDD(3V3) and VDDA(3V3)) for I/O and ADC reference. The analog grounds (VSSA, VSSA(PLL)) must be isolated from digital ground to maintain ADC accuracy and PLL stability in the LPC2119FBD64,151.

Can the LPC2119FBD64,151 perform in-system programming (ISP)?

Yes, the LPC2119FBD64,151 supports In-System Programming via its UART0 interface using the on-chip bootloader. Flash programming takes 1 ms per 512-byte line, and sector or full-chip erase completes in 400 ms. This ISP capability enables field firmware updates without removing the LPC2119FBD64,151 from the target board - critical for remote maintenance and security patching.

Is the LPC2119FBD64,151 pin-compatible with other LPC21xx devices?

The LPC2119FBD64,151 shares the same LQFP64 package (SOT314-2) and identical pin configuration with LPC2109FBD64,151 and LPC2129FBD64,151, including matching power, reset, oscillator, and peripheral pin assignments. However, functional differences exist - such as flash size, SRAM, and CAN channel count - so firmware and power design must be verified per device; the LPC2119FBD64,151 is mechanically and electrically pin-compatible but not functionally identical.
