1 Feature Differences Between F28002x and F28003x

F28003x is a superset of F28002x. They have three packages in common, 48-pin, 64-pin and 80-pin. It is possible to migrate between F28003x and F28002x with the caveats in this document taken into account.

Note: This comparison guide focuses on the super-set devices: F280025 and F280039. Other part numbers in this product family have reduced feature support. For details specific to part numbers, see the device-specific data sheet.

2 PCB Hardware Changes

The F28002x and F28003x devices have three packages in common: 80-pin PN, 64-pin PM and 48-pin PT. The following sections describe the pin migration in detail.

Note: Overall compatibility depends on more than just the pins. Review all of the changes in this document during the migration process.

2.1 PCB Hardware Changes for the 80-Pin PN, 64-Pin PM and 48-Pin PT Packages

This section describes the F28003x and F28002x differences that exist between the 80-Pin PN, 64-Pin PM and 48-Pin PT packages.

80-Pin PN: The Q and non-Q variant for F28002x have the same pinout whereas F28003x has no Q variant for 80-Pin PN. Figure 2-1 outlines the differences.

64-Pin PM: The Q and non-Q variant for F28002x have the same pinout whereas VREGENZ replaces GPIO39 in the Q variant for F28003x. Figure 2-2 and Figure 2-3 outline the differences.

48-Pin PT: The Q and non-Q variant have the same pinout for both devices. Figure 2-4 outlines the differences.

3 Feature Differences for System Consideration

The differences and similarities that exist when moving between the F28003x and F28002x devices is explored in this section.

3.1 New Features in F28003x

This section outlines features that only exist in the F28003x device. For details on each of these new features, see the TMS320F28003x Real-Time Microcontrollers Technical Reference Manual (SPRUIW9).

3.1.1 Advance Encryption Standard (AES)

The AES module on F28003x is a symmetric cipher module that provides hardware-accelerated data encryption and decryption with support for 128-, 192- and 256-bit keys. AES was first introduced in F2838x.

3.1.2 Secure Boot/JTAG Lock

The F28003x device supports secure booting and also has the capability to lock the JTAG to avoid debug access thereby enhancing security. Secure Boot and JTAG Lock were first introduced in F2838x.

3.1.3 Modular Controller Area Network (MCAN)

The MCAN module on F28003x supports CAN FD (CAN with the flexible data-rate) specification which has a higher throughput compared to Classic CAN. It can also operate in Classic CAN mode if needed. MCAN was first introduced in F2838x.

3.1.4 Embedded Pattern Generator (EPG)

The EPG on F28003x is an interface module that can be used to generate waveforms and clocks for other modules on the device. This can be useful for communication module diagnostics and also providing the modulation clock for the SDFM.

3.1.5 Live Firmware Update (LFU)

The F28003x device has in-built hardware to facilitate live firmware updates. It supports fast context switching from the old firmware to the new firmware to minimize application downtime when updating the device firmware.

3.2 Communication Module Changes

Communication module changes between the F28002x and F28003x devices affect the number of modules, addition of CAN-FD and some differences in HIC and FSI. Details are available in Table 3-1.

3.3 Control Module Changes

There are minimal changes in the control modules between the F28002x and F28003x devices. The biggest change is the addition of an SDFM module for the F28003x device. Table 3-2 shows the module instances differences which should be considered when migrating applications between F28002x and F28003x.
