TMP1942FD
TMP1942FD-2
(1) TX19 core processor
1) Two instruction set architecture (ISA) modes: 16-bit ISA for code efficiency and 32-bit ISA
for performance.
The 16-bit ISA is object-code compatible with the code-efficient MIPS16TM ASE.
The 32-bit ISA is object-code compatible with the high-performance TX39 family.
2) High performance combined with low power consumption
-
High performance
Single clock cycle execution for most instructions
3-operand arithmetic instructions for high instruction throughput
5-stage pipeline
On-chip high-speed memory
DSP function: Executes 32-bit x 32-bit multiply operations in a single clock cycle.
-
Low power consumption
Optimized design using a low-power cell library
Programmable standby modes in which processor clocks are stopped
3) Fast interrupt response suitable for real-time control
Distinct starting locations for each interrupt service routine
Automatically generated vectors for each interrupt source
Automatic updates of the interrupt mask level
(
2) On-chip RAM:
TMP1942FDU/FDXB
20 KB
On-chip FROM
TMP1942FDU/FDXB
512 KB
ROM correction function (8 words x 4 blocks)
(
In the flash-version product, only the registers exist and no correction is performed.)
(
3) External memory expansion
16-Mbyte off-chip address space for code and data
External bus interface with dynamic bus sizing for 8-bit and 16-bit data ports
(
4) 4-channel DMA controller
Interrupt- or software-triggered
(
5) 6-channel 8-bit PWM timer
12-channel 8-bit interval timer
6-channel 16-bit interval timer
6-channel 8-bit PPG output
(
6) 14-channel 16-bit timer
Two channels support two-phase input pulse counter mode.
(
7) 1-channel RTC timer
(
8) 5-channel general-purpose serial interface
Supports both UART and synchronous transfer modes.
