13.1 Introduction

This chapter highlights the major differences (in terms of features/peripherals)

between the ’240x and the ’24x (TMS320F243/’F241/’C242) family of DSP de-

vices. The ’240x devices share most of the ’24x features; however, ’240x de-

vices have some enhancements. The common features, differences, and en-

hancements are described in Table 13–1 and Table 13–2.
