device numbering conventions

Figure 12 illustrates the numbering and symbol nomenclature for the TMS370Cx0x family.

370

0 2

Prefix: TMS = Standard prefix for fully qualified devices

SE = System evaluator that is used for

prototyping purpose.

Family:

370 = TMS370 8-Bit Microcontroller Family

Technology:

C = CMOS

Program Memory Types:

0 = Mask ROM

3 = Mask ROM, No Data EEPROM

7 = EPROM

Device Type:

0 = ’x0x devices containing the following modules:

— Timer 1

— Serial Communications Interface 1 (SCI1)

Memory Size:

2 = 8K bytes

Temperature Ranges:

A = –40

°Cto 85°C

°Cto 70°C

T = –40

°C to 105°C

Packages:

FN = Plastic Leaded Chip Carrier

FZ = Ceramic Leaded Chip Carrier

ROM and EPROM Option:

A = For ROM device, the watchdog timer can be configured

as one of the three different mask options:

– A standard watchdog

– A hard watchdog

– A simple watchdog

The clock mask option can be either:

– Divide-by-4 clock

– Divide-by-1 (PLL) clock

The low-power modes can be either:

– Enabled

– Disabled

NONE = For EPROM device, a standard watchdog, a

divide-by-4 clock, and low-power modes are enabled.
