The values specified are when VDD = 3.3 V and VCCP = 5 V, and any deviation from these values could affect the timing parameters. Aging and process variance could also impact the timing parameters. migrating from LF240xA (Flash) devices to LC240xA (ROM) devices When migrating from a Flash to a ROM device, be sure to review this section for a list of important differences that should be considered. Customer applications should consider these differences in their design, prior to ROM code submission. Due to the fact that the flash and ROM are different silicon, the following parameters may be similar but not exactly identical. Refer to the respective datasheet sections for more detail: D EMI/ESD behavior D ADC performance D Current consumption D Device ID register values Table 18 outlines the differences between the LF240xA (Flash) devices and the LC240xA (ROM) devices.

See the SPI Slave Mode Operation in LF2403A section. ¶ Application code should NOT access Illegal/Reserved addresses. NOTES: 1. Access to external Program, Data, and I/O space is considered illegal and would assert an NMI. 2. The external Program and I/O spaces are implemented as “reserved” addresses and any access will not assert an NMI. However, the external data memory space is illegal. |
