Product details
Overview
SW300003-EVAL from Microchip Technology is an evaluation-license software package implementing the ITU-T V.32bis data modem algorithm for dsPIC30F digital signal controllers, supporting full-duplex QAM/TCM modulation at up to 14.4 kbps, with integrated V.42 LAPM error correction and AT command interface - deployed in industrial metering, fire panels, and internet-connected vending machines.
For engineers reviewing the SW300003-EVAL datasheet, SW300003-EVAL application scope, SW300003-EVAL licensing terms, or SW300003-EVAL functional equivalence to production versions (SW300003/SW300004), this page details its supported modulations, memory footprint, host integration requirements, fallback behavior, and evaluation-specific constraints.
Technical Context
SW300003-EVAL implements V.32bis at 2400 symbols/sec on a 1800 Hz carrier with trellis-coded modulation (TCM) across all rates except 4800 bps, and includes optional fallback to V.22bis, V.22, V.23, and V.21 standards. It integrates V.42 LAPM link-layer error correction and a C-language AT Command Set API.
The library targets single-channel data-pump implementations on dsPIC30F devices, with all data pump modules written in ASM30 assembly for minimal MIPS and memory overhead, while V.42, DP, and AT APIs are implemented in C30 C language and linked against user applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 14.4 kbps maximum full-duplex rate; enables high-throughput telemetry in constrained-bandwidth PSTN links. |
| Modulation | QAM/TCM (Trellis-Coded Modulation); provides robust noise immunity and spectral efficiency over analog phone lines. |
| Fallback Standards | V.22bis, V.22, V.23, V.21; ensures interoperability and link resilience under degraded line conditions. |
| Memory Usage | 36 Kbytes program memory, 3.6 Kbytes data memory; fits within typical dsPIC30F5011/6014 resource budgets. |
| Processing Load | 15 MIPS peak execution; requires dsPIC30F running ≥30 MIPS to sustain real-time V.32bis operation. |
| Error Correction | V.42 LAPM protocol included; delivers link-level ARQ and bit-error recovery without external protocol stack dependency. |

FAQ
What is the license duration for SW300003-EVAL?
The SW300003-EVAL license is valid for one year from activation. It grants full access to the V.32bis modem library source and object code, including V.42 LAPM and AT Command Set APIs, with identical functionality to production versions - but prohibits deployment in commercial products beyond evaluation use.
Which dsPIC30F devices are supported by SW300003-EVAL?
SW300003-EVAL targets dsPIC30F devices with ≥30 MIPS performance and sufficient RAM/Flash (e.g., dsPIC30F5011, dsPIC30F6014). Hardware drivers for UART and DAA/AFE interfaces are provided in assembly source code and must be adapted to the specific dsPIC30F variant's peripheral register map.
Does SW300003-EVAL include source code for the V.32bis data pump?
No - SW300003-EVAL delivers the V.32bis/V.32 data pump in object code only, consistent with Microchip's licensing model for higher-speed modems. In contrast, V.22bis/V.22 libraries (e.g., SW300002) ship with full assembly source. V.42, DP, and AT APIs remain in C source form.
Can SW300003-EVAL operate without V.42 error correction?
Yes - SW300003-EVAL supports both V.42-enabled and V.42-bypass modes. The V.42 module is optional and consumes 14 Kbytes program memory and 2.0 Kbytes data memory; disabling it reduces memory footprint but removes link-layer ARQ and HDLC framing.
How does SW300003-EVAL differ from SW300003 (production license)?
SW300003-EVAL and SW300003 share identical algorithm implementation, API surface, and fallback behavior. The sole difference is licensing: SW300003-EVAL is time-limited (1 year) and restricted to evaluation use, whereas SW300003 permits unlimited deployment up to 5,000 units per project under a one-time fee.
