(95°C, 16MHz, 15% Toggle)DescriptionThe IA80C152 is a Universal Communications Controller (UCC) that is pin-for-pin compatible ith the Intelä 80C152. This version of the UCC is a ROMless version. The ROM version is dentified as the 83C152 and can be easily derived from the 80C152 using a customer furnished OM program. The IA80C152 can be programmed with the same software development tools and an transmit and receive using the same communication protocols as the Intelä 80C152 making the A80C152 a drop-in replacement. Table 1 below cross-references IA80C152 versions with rotocol, package, and I/O Port capability. Pinout diagrams are provided in figures 1, 2, and 3.
The only difference between The innovASIC 80C152 and the Intelä 80C152 is that all protocols re available in all IC versions. Originally, the Intelä 80C152 JC and JD versions were limited to DLC/HDLC only. Also, innovASIC will support a ROM version (83152) in any of the JA, JB, JC, r JD versions.
The IA80C152 is partitioned into three major functional units identified as the C8051, the Direct emory Access (DMA) Controller, and the Global Serial Channel (GSC). The C8051 is mplemented using a CAST, Inc. Intellectual Property (IP) core. This core is instruction set ompatible with the 80C51BH, and contains compatible peripherals including a UART interface nd timers. The special function registers (SFRs) and interrupts are modified from the original 051BH to accommodate the additional DMA controller and GSC peripherals.
The DMA Controller of the IA80C152 is a 2 channel, 8-bit device that is 16-bit addressable. Either channel can ccess any combination of reads and writes to external memory, internal memory, or the SFR's. arious modes allow the DMA to access the UART, GSC, SFRs, and internal and external memory s well as provide for external control. Since there is only 1 data/program memory bus, only one MA channel or the microcontroller can have control at any give time. Arbitration within the evice makes this control transparent to the programmer.
