3 / 105 page TMP19A43 TMP19A43 (rev2.0) 1-2 Overview and Features (1) TX19A processor core 1) Improved code efficiency and operating performance have been realized through the use of two ISA (Instruction Set Architecture) modes - 16- and 32-bit ISA modes. • The 16-bit ISA mode instructions are compatible with the MIPS16 TMASE instructions of superior code efficiency at the object level. • The 32-bit ISA mode instructions are compatible with the TX39 instructions of superior operating performance at the object level. 2) Both high performance and low power dissipation have been achieved. High performance • Almost all instructions can be executed with one clock. • High performance is possible via a three-operand operation instruction. • 5-stage pipeline • Built-in high-speed memory • DSP function: A 32-bit multiplication and accumulation operation can be executed with one clock. Low power dissipation • Optimized design using a low power dissipation library • Standby function that stops the operation of the processor core 3) High-speed interrupt response suitable for real-time control • Independency of the entry address • Automatic generation of factor-specific vector addresses • Automatic update of interrupt mask levels (2) Internal program memory and data memory Product name Built-in ROM Built-in RAM TMP19A43CZXBG 384Kbyte 20Kbyte TMP19A43CDXBG * 512Kbyte 24Kbyte TMP19A43FZXBG * 384Kbyte (Flash) 20Kbyte TMP19A43FDXBG 512Kbyte (Flash) 24Kbyte The product indicated by an asterisk * is under development. • ROM correction function: 1 word × 8 blocks, 8 words × 4 blocks (3) External memory expansion • Expandable to 16 megabytes (for both programs and data) • External data bus: Separate bus/multiplexed bus : Coexistence of 8- and 16-bit widths is possible. Chip select/wait controller : 4 channels (4) DMA controller : 8 channels (2 interrupt factors) • Activated by an interrupt or software • Data to be transferred to internal memory, internal I/O, external memory, and external I/O (5) 16-bit timer : 16 channels • 16-bit interval timer mode • 16-bit event counter mode • 16-bit PPG output (every 4 channels, synchronous outputs are possible) • Input capture function • 2-phase pulse input counter function (4 channels assigned to perform this function): Multiplication- by-4 mode |
