4 / 49 page TMS370Cx0x 8-BIT MICROCONTROLLER SPNS029C – SEPTEMBER 1995 – REVISED FEBRUARY 1997 4 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 description (continued) Table 1. Memory Configurations DEVICE PROGRAM MEMORY (BYTES) DATA MEMORY (BYTES) 28-PIN PACKAGE ROM EPROM RAM EEPROM TMS370C002A 8K — 256 256 FN – PLCC TMS370C302A 8K — 256 — FN – PLCC TMS370C702 — 8K 256 256 FN – PLCC SE370C702† — 8K 256 256 FZ – CLCC † System evaluators and development are for use only in prototype environment and their reliability has not been characterized. The suffix letter (A) appended to the device name (shown in the first column of Table 1) indicates the configuration of the device. ROM and EPROM devices have different configurations as indicated in Table 2. ROM devices with the suffix letter A are configured through a programmable contact during manufacture. Table 2. Suffix Letter Configuration DEVICE WATCHDOG TIMER CLOCK LOW-POWER MODE EPROM without A Standard Divide-by-4 (standard oscillator) Enabled Standard Di id b 4 ROM A Hard Divide-by-4 or Divide-by-1 (PLL) Enabled or disabled Simple Divide-by-1 (PLL) The 8K bytes of mask-programmable ROM in the associated TMS370Cx0x devices are replaced in the TMS370C702 with 8K bytes of EPROM. All other available memory and on-chip peripherals are identical, with the exception of no data EEPROM on the TMS370C302 devices. The one-time programmable (OTP) (TMS370C702) device and reprogrammable device (SE370C702) are available. TMS370C702 OTP devices are available in plastic packages. This microcontroller is effective to use for immediate production updates for other members of the TMS370Cx0x family or for low-volume production runs when the mask charge or cycle time for low-cost mask ROM devices is not practical. The SE370C702 has a windowed ceramic package to allow reprogramming of the program EPROM memory during the development-prototyping phase of design. The SE370C702 devices allow quick updates to breadboards and prototype systems while iterating initial designs. The TMS370Cx0x family provides two low-power modes (STANDBY and HALT) for applications where low-power consumption is critical. Both modes stop all CPU activity (that is, no instructions are executed). In the STANDBY mode, the internal oscillator and the general purpose timer remain active. In the HALT mode, all device activity is stopped. The device retains all RAM data and peripheral configuration bits throughout both low-power modes. The TMS370Cx0x features advanced register-to-register architecture that allows direct arithmetic and logical operations without requiring an accumulator (for example, ADD R24, R47; add the contents of register 24 to the contents of register 47 and store the result in register 47). The TMS370Cx0x family is fully instruction-set-compatible, providing easy transition between members of the TMS370 8-bit microcontroller family. The TMS370Cx0x devices have two operational modes of serial communications provided by the SCI1 module. The SCI1 allows standard RS-232-C communications with other common data transmission equipment. |
